Digital Holography Using a Laser Pointer and Consumer Digital Camera Report Date: June 22Nd, 2004
Digital Holography using a Laser Pointer and Consumer Digital Camera Report date: June 22nd, 2004 by David Garber, M.E. undergraduate, Johns Hopkins University, [email protected] Available online at http://pegasus.me.jhu.edu/~lefd/shc/LPholo/lphindex.htm Acknowledgements Faculty sponsor: Prof. Joseph Katz, [email protected] Project idea and direction: Dr. Edwin Malkiel, [email protected] Digital holography reconstruction: Jian Sheng, [email protected] Abstract The point of this project was to examine the feasibility of low-cost holography. Can viable holograms be recorded using an ordinary diode laser pointer and a consumer digital camera? How much does it cost? What are the major difficulties? I set up an in-line holographic system and recorded both still images and movies using a $600 Fujifilm Finepix S602Z digital camera and a $10 laser pointer by Lazerpro. Reconstruction of the stills shows clearly that successful holograms can be created with a low-cost optical setup. The movies did not reconstruct, due to compression and very low image resolution. Garber 2 Theoretical Background What is a hologram? The Merriam-Webster dictionary defines a hologram as, “a three-dimensional image reproduced from a pattern of interference produced by a split coherent beam of radiation (as a laser).” Holograms can produce a three-dimensional image, but it is more helpful for our purposes to think of a hologram as a photograph that can be refocused at any depth. So while a photograph taken of two people standing far apart would have one in focus and one blurry, a hologram taken of the same scene could be reconstructed to bring either person into focus. -

Information capacity: a measure of potential image quality of a digital camera Frédéric Cao 1, Frédéric Guichard, Hervé Hornung DxO Labs, 3 rue Nationale, 92100 Boulogne Billancourt, FRANCE ABSTRACT The aim of the paper is to define an objective measurement for evaluating the performance of a digital camera. The challenge is to mix different flaws involving geometry (as distortion or lateral chromatic aberrations), light (as luminance and color shading), or statistical phenomena (as noise). We introduce the concept of information capacity that accounts for all the main defects than can be observed in digital images, and that can be due either to the optics or to the sensor. The information capacity describes the potential of the camera to produce good images. In particular, digital processing can correct some flaws (like distortion). Our definition of information takes possible correction into account and the fact that processing can neither retrieve lost information nor create some. This paper extends some of our previous work where the information capacity was only defined for RAW sensors. The concept is extended for cameras with optical defects as distortion, lateral and longitudinal chromatic aberration or lens shading. Keywords: digital photography, image quality evaluation, optical aberration, information capacity, camera performance database 1. INTRODUCTION The evaluation of a digital camera is a key factor for customers, whether they are vendors or final customers. It relies on many different factors as the presence or not of some functionalities, ergonomic, price, or image quality. Each separate criterion is itself quite complex to evaluate, and depends on many different factors. The case of image quality is a good illustration of this topic. -

Passport Photograph Instructions by the Police
Passport photograph instructions 1 (7) Passport photograph instructions by the police These instructions describe the technical and quality requirements on passport photographs. The same instructions apply to all facial photographs used on the passports, identity cards and permits granted by the police. The instructions are based on EU legislation and international treaties. The photographer usually sends the passport photograph directly to the police electronically, and it is linked to the application with a photograph retrieval code assigned to the photograph. You can also use a paper photograph, if you submit your application at a police service point. Contents • Photograph format • Technical requirements on the photograph • Dimensions and positioning • Posture • Lighting • Expressions, glasses, head-wear and make-up • Background Photograph format • The photograph can be a black-and-white or a colour photograph. • The dimensions of photographs submitted electronically must be exactly 500 x 653 pixels. Deviations as small as one pixel are not accepted. • Electronically submitted photographs must be saved in the JPEG format (not JPEG2000). The file extension can be either .jpg or .jpeg. • The maximum size of an electronically submitted photograph is 250 kilobytes. 1. Correct 2.

Excerpt from the Hanford Photographs
“Horace Hanford and the History of Photography” Excerpt from: The Hanford Photographs A Catalogue of the Photographic Collection at Hanford Mills Museum Copyright ©1990 Introduction Like many Americans in the final decade of the nineteenth century, residents of East Meredith, New York were fascinated by photography. What once had been the exclusive domain of professional studio photographers became part of everyday life. The camera appeared in the workplace, at family outings, and other social events, recording the intimate as well as the public scenes of people’s lives. In East Meredith and neighboring towns, a number of individuals had begun experimenting with photography by 1890. The hundreds of prints by local photographers which have survived attest to the popularity of the activity. Still, many images probably were discarded, not recognized for the value they would hold for succeeding generations. Fortunately, the photographic images of Horace Hanford have survived. His glass plate negatives provide a picture of life in East Meredith over a period of thirty years. Perusing the images, one senses that the viewer is looking over Horace’s shoulder as he took the photographs. They bring the viewer into his world to share his point of view. The Popular Art of Photography “Photography is growing more and more in favor the world over. It affords greater attraction than all the arts heretofore introduced in popular form, for while it answers fully the requirements of mechanical taste, it offers constant opportunities for the exercise of other intellectual quali- ties.” Rochester Optical Company Catalog, 1898 This enthusiastic statement neatly summarizes the status of photography in the last decade of the nineteenth century. -
