  • Multi-Wavelength Compressive Computational Ghost Imaging
    Multi-wavelength compressive computational ghost imaging Stephen S. Welsha , Matthew P. Edgara, Phillip Jonathanb , Baoqing Suna , Miles. J. Padgetta aUniversity of Glasgow, Kelvin Building University Avenue G12 8QQ, Glasgow, UK; bDepartment of Mathematics and Statistics, Lancaster University, Lancaster, LA1 4YF, UK; ABSTRACT The field of ghost imaging encompasses systems which can retrieve the spatial information of an object through correlated measurements of a projected light field, having spatial resolution, and the associated reflected or trans- mitted light intensity measured by a photodetector. By employing a digital light projector in a computational ghost imaging system with multiple spectrally filtered photodetectors we obtain high-quality multi-wavelength reconstructions of real macroscopic objects. We compare different reconstruction algorithms and reveal the use of compressive sensing techniques for achieving sub-Nyquist performance. Furthermore, we demonstrate the use of this technology in non-visible and fluorescence imaging applications. Keywords: Ghost Imaging, Single Pixel Detectors, DLP Technologies, Multi-wavelength Imaging, Non-visible Imaging, Fluorescence Imaging 1. INTRODUCTION Ghost imaging (GI) has been an active research area for nearly two decades. First demonstrated utilizing spatially entangled photons,1 it was later shown possible using classical correlations of pseudo-thermal light sources.2{5 Early demonstrations of so called `classical GI' used a laser beam propagated through a ground glass diffuser in order to produce a pseudo-thermal speckle field. A beam splitter was used to produce two identical copies of the field which were subsequently propagated along two different paths: the test path and the reference path. The test path contained a partially transmissive or reflective object (typically planar) and a single-pixel photodetector (SPD) with no spatial resolution, whereas the reference path contained a detector with spatial resolution, typically a charged coupled device (CCD).

    1 Lensless Imaging with Compressive Ultrafast Sensing Guy Satat, Matthew Tancik and Ramesh Raskar Abstract—Lensless imaging is an important and challenging time: the physics-based approach is done in one shot (i.e. all problem. One notable solution to lensless imaging is a single the sensing is done in parallel). The single pixel camera and pixel camera which benefits from ideas central to compressive its variants require hundreds of consecutive acquisitions, which sampling.

Here we consider a time-resolved system with different illumination pattern and produces a time series where pulsed active illumination combined with a sensor with a time is a function of the photon’s origin in the scene. Currently time resolution on the order of picoseconds. Picosecond time available hardware with picosecond time resolution enables time tagging photons as they arrive to an omnidirectional sensor. resolution allows distinguishing between photons that arrive This allows lensless imaging with significantly fewer patterns from different parts of the target with mm resolution. The compared to regular single pixel imaging. To that end, we develop sensor provides more information per acquisition (compared a framework for designing lensless imaging systems that use to regular pixel), and so fewer masks are needed. Moreover, the ultrafast detectors. We provide an algorithm for ideal sensor time-resolved sensor is characterized by a measurement matrix placement and an algorithm for optimized active illumination patterns.

  • Fast First-Photon Ghost Imaging
    www.nature.com/scientificreports OPEN Fast frst-photon ghost imaging Xialin Liu, Jianhong Shi, Xiaoyan Wu & Guihua Zeng Conventional imaging at low light levels requires hundreds of detected photons per pixel to suppress the Poisson noise for accurate refectivity inference. We propose a high-efciency photon-limited imaging technique, called fast frst-photon ghost imaging, which recovers the image by conditional Received: 11 December 2017 averaging of the reference patterns selected by the frst-photon detection signal. Our technique merges the physics of low-fux measurements with the framework of computational ghost imaging. Accepted: 9 March 2018 Experimental results demonstrate that it can reconstruct an image from less than 0.1 detected photon Published: xx xx xxxx per pixel, which is three orders of magnitude less than conventional imaging techniques. A signal- to-noise ratio model of the system is established for noise analysis. With less data manipulation and shorter time requirements, our technique has potential applications in many felds, ranging from biological microscopy to remote sensing. Photon-limited imaging has attracted great interest on account of its important applications under extreme envi- ronments, such as night vision1, biological imaging2, remote sensing3, and so forth, when of-the-shelf methods fail due to photon-limited data. Conventionally, the transverse spatial image is recovered by either a spatially resolving detector array with foodlight illumination or a single detector with raster-scanned point-by-point illumination. In this way, even with time-resolved single-photon detectors, hundreds of photons per pixel are necessary to suppress the Poisson noise that is inherent in photon counting to obtain accurate intensity values.

In electron microscopy, such concepts have not yet been explored extensively. For example, inelastic scattering can be reanalyzed in terms of correlations between an electron beam and a sample. Whereas classical inelastic scattering results in a loss of coherence in the electron beam, a joint measurement performed on both the electron beam and the sample excitation could restore the coherence and “lost information.” Here, we propose to exploit joint measurement in electron microscopy to achieve a counterintuitive application of the concept of ghost imaging, which was first proposed in quantum photonics.

  • Direct Generation and Detection of Correlated Photons with 3.2 Um Wavelength Spacing

Existing techniques for correlated photons have been concentrated in the visible and near- IR domains, with the photon pairs residing within one micron. Here, we demonstrate direct generation and detection of high-purity photon pairs at room temperature with 3.2 um wave- length spacing, one at 780 nm to match the rubidium D2 line, and the other at 3950 nm that falls in a transparent, low-scattering optical window for free space applications. The pairs arXiv:1708.05909v2 [physics.optics] 13 Sep 2017 are created via spontaneous parametric downconversion in a lithium niobate waveguide with specially designed geometry and periodic poling. The 780 nm photons are measured with a silicon avalanche photodiode, and the 3950 nm photons are measured with an upconver- 1 sion photon detector using a similar waveguide, which attains 34% internal conversion ef- ficiency. Quantum correlation measurement yields a high coincidence-to-accidental ratio of 54, which indicates the strong correlation with the extremely non-degenerate photon pairs.

Ghost imaging has great potential to provide robust imaging solutions in the presence of severe environmental perturbations, and has been demonstrated both in the spatial [3-10] and temporal domains [11–13]. Here, we exploit recent progress in ultrafast real-time measurement techniques [14] to demonstrate ghost imaging in the frequency domain using a continuous spectrum from an incoherent supercontinuum (SC) light source. We demonstrate the particular application of this ghost imaging technique to broadband spectroscopic measurements of methane absorption, and our results offer novel perspectives for remote sensing in low light conditions, or in spectral regions where sensitive detectors are lacking. Ghost imaging is based on correlating two signals: the spatially-resolved intensity pattern of a light source incident on the object (a probe pattern), and the total integrated intensity scattered from the illuminated object. The image is generated by summing over multiple incident patterns, each weighted by the integrated scattered signal.

In parallel, the quantum nature of the transverse electromagnetic field has spawned the field of quantum imaging that encompasses technologies such as quantum lithog- raphy, quantum ghost imaging, and high-dimensional quantum key distribution (QKD). The emergence of such quantum technologies also highlights the need for the development of accurate and efficient methods of measuring and characterizing the elusive quantum state itself. In this paper, we describe new technologies that use the quantum properties of light for security. The first of these is a technique that extends the principles behind QKD to the field of imaging and optical rang- ing. By applying the polarization-based BB84 protocol to individual photons in an active imaging system, we obtained images that are secure against any intercept- resend jamming attacks. The second technology presented in this article is based on an extension of quantum ghost imaging, a technique that uses position-momentum entangled photons to create an image of an object without directly obtaining any spatial information from it.

  • Experimental Limits of Ghost Diffraction
    www.nature.com/scientificreports OPEN Experimental Limits of Ghost Difraction: Popper’s Thought Experiment Received: 20 April 2018 Paul-Antoine Moreau1, Peter A. Morris1, Ermes Toninelli1, Thomas Gregory1, Accepted: 16 August 2018 Reuben S. Aspden1, Gabriel Spalding 2, Robert W. Boyd1,3,4 & Miles J. Padgett1 Published: xx xx xxxx Quantum ghost difraction harnesses quantum correlations to record difraction or interference features using photons that have never interacted with the difractive element. By designing an optical system in which the difraction pattern can be produced by double slits of variable width either through a conventional difraction scheme or a ghost difraction scheme, we can explore the transition between the case where ghost difraction behaves as conventional difraction and the case where it does not. For conventional difraction the angular extent increases as the scale of the difracting object is reduced. By contrast, we show that no matter how small the scale of the difracting object, the angular extent of the ghost difraction is limited (by the transverse extent of the spatial correlations between beams). Our study is an experimental realisation of Popper’s thought experiment on the validity of the Copenhagen interpretation of quantum mechanics. We discuss the implication of our results in this context and explain that it is compatible with, but not proof of, the Copenhagen interpretation. Quantum ghost difraction was introduced together with ghost imaging by Shih and co-workers in 19951,2. Tese “ghost” experiments refer to confgurations where the image or difraction pattern is obtained from a spatial dis- tribution of photons that have not themselves interacted with the object.

  • Polarimetry by Classical Ghost Diffraction
    Polarimetry by classical ghost diffraction Henri Kellock1,∗ Tero Setälä1, Ari T. Friberg1, and Tomohiro Shirai2 1Institute of Photonics, University of Eastern Finland, P.O. Box 111, FI-80101 Joensuu, Finland 2Research Institute of Instrumentation Frontier, National Institute of Advanced Industrial Science and Technology, AIST Tsukuba Central 2, 1-1-1 Umezono, Tsukuba 305-8568, Japan We present a technique for studying the polarimetric properties of a birefringent object by means of classical ghost diffraction. The standard ghost diffraction setup is modified to include polarizers for controlling the state of polarization of the beam in various places. The object is characterized by a Jones matrix and the absolute values of the Fourier transforms of its individual elements are measured. From these measurements the original complex-valued functions can be retrieved through iterative methods resulting in the full Jones matrix of the object. We present two different placements of the polarizers and show that one of them leads to better polarimetric quality, while the other place- ment offers the possibility to perform polarimetry without controlling the source’s state of polariza- tion. The concept of an effective source is introduced to simplify the calculations. Ghost polarimetry enables the assessment of polarization properties as a function of position within the object through simple intensity correlation measurements. I. INTRODUCTION applications (such as thin-film optics and nanophoton- ics) a simpler polarimetric characterization of the object Ghost imaging, or correlation imaging, is an imaging by means of its Jones matrix is adequate.

Featured Application: The speckle binarization is the key process in binary ghost imaging and it can influence the imaging resolution and the contrast of the reconstruction results. Based on the finding in this study, the binary ghost imaging can reconstruct the image of target with high quality, which is beneficial to the application of binary ghost imaging in practice. Abstract: The reconstruction quality of binary ghost imaging depends on the speckle binarization process. In order to obtain better binarization speckle and improve the reconstruction quality of binary ghost imaging, a local adaptive binarization method based on the fuzzy integral is proposed in this study. There are three steps in the proposed binarization process. The first step is to calculate the integral image of the speckle with the summed-area table algorithm. Secondly, the fuzzy integral image is calculated through the discrete Choquet integral. Finally, the binarization threshold of each pixel of the speckle is selected based on the calculated fuzzy integral result.

  • Lost Photon Enhances Superresolution
    Lost photon enhances superresolution A. Mikhalychev,1, ∗ P. Novik,1 I. Karuseichyk,1 D. A. Lyakhov,2 D. L. Michels,2 and D.

In partic- ular, it is known that one can reduce the image blurring and increase the achievable resolution by illuminating an object by entangled light and measuring coincidences of photons. If an n-photon entangled state is used and the pnth-order correlation function is measured, the point-spread func- tion (PSF) effectively becomes n times narrower relatively to classical coherent imaging. Quite surprisingly, measuring n-photon correlations is not the best choice if an n-photon entangled state is available. We show that for measuring (n − 1)-photon coincidences (thus, ignoring one of the available photons), PSF can be made even narrower. This observation paves a way for a strong conditional resolution enhancement by registering one of the photons outside the imaging area. We analyze the conditions necessary for the resolution increase and propose a practical scheme, suitable for observation and exploitation of the effect. Diffraction of light limits the spatial resolution of clas- only n − 1 remaining photons. According to our results, sical optical microscopes [1, 2] and hinders their applica- measurement of (n − 1)th-order correlations effectively bility to life sciences at very small scales.
