  • Optics – Panoramic Lens Applications Revisited
    Panoramic Lens Applications Revisited Simon Thibault* M.Sc., Ph.D., Eng Director, Optics Division/Principal Optical Designer ImmerVision 2020 University, Montreal, Quebec, H3A 2A5 Canada ABSTRACT During the last few years, innovative optical design strategies to generate and control image mapping have been successful in producing high-resolution digital imagers and projectors. This new generation of panoramic lenses includes catadioptric panoramic lenses, panoramic annular lenses, visible/IR fisheye lenses, anamorphic wide-angle attachments, and visible/IR panomorph lenses. Given that a wide-angle lens images a large field of view on a limited number of pixels, a systematic pixel-to-angle mapping will help the efficient use of each pixel in the field of view. In this paper, we present several modern applications of these modern types of hemispheric lenses. Recently, surveillance and security applications have been proposed and published in Security and Defence symposium. However, modern hemispheric lens can be used in many other fields. A panoramic imaging sensor contributes most to the perception of the world. Panoramic lenses are now ready to be deployed in many optical solutions. Covered applications include, but are not limited to medical imaging (endoscope, rigiscope, fiberscope…), remote sensing (pipe inspection, crime scene investigation, archeology…), multimedia (hemispheric projector, panoramic image…). Modern panoramic technologies allow simple and efficient digital image processing and the use of standard image analysis features (motion estimation, segmentation, object tracking, pattern recognition) in the complete 360o hemispheric area. Keywords: medical imaging, image analysis, immersion, omnidirectional, panoramic, panomorph, multimedia, total situation awareness, remote sensing, wide-angle 1. INTRODUCTION Photography was invented by Daguerre in 1837, and at that time the main photographic objective was that the lens should cover a wide-angle field of view with a relatively high aperture1.

  • 6 Tips for Near-Macro Photography with a Telephoto Lens a Post By: Elliot Hook
    6 Tips for Near-Macro Photography with a Telephoto Lens A Post By: Elliot Hook Macro photography is the art of capturing the fine detail of very small subjects that may not be able to be seen by the naked eye. Technically, to fall under the term ‘macro’, the subject should be captured with a reproduction ratio of 1:1, i.e. the subject will be captured on the sensor at 100 % life size. Macro lenses are specially designed to minimise the focussing distance, allowing the photographer to get closer to the subject and so increase the reproduction ratio. There are a number of other techniques that can be used to help achieve the desired magnification without a dedicated lens (extension tubes, close-up filters, reversing rings), however, one of less often considered techniques is to use something that you probably already have in your kit bag: a telephoto lens. Milking Bonnet Fungi (Mycena galopus) Telephoto lenses offer extreme magnification but generally have much larger minimum focussing distances pushing the photographer further from the subject and so reducing the reproduction ratio. Some telephoto lenses, when combined with camera systems utilising smaller sensors, are able to offer 1:1 magnification (‘true macro’) however, typically, telephoto lenses are limited to close-up photography, at near-macro reproduction ratios. Using a telephoto lens for this kind of work offers a couple of advantages over a dedicated macro lens that are a direct result of the large minimum focus distance. Because the working distance to the subject is in the region of 1 metre (compared to 15 – 30 cm of standard macro lenses) the risk of disturbing your subject as you compose your shot is much reduced.

The lens on a camera is a series of precision-shaped pieces of glass that, when placed together, can manipulate light and change the appearance of an image. Some cameras have removable lenses (interchangeable lenses) while other cameras have permanent lenses (fixed lenses). Fixed-lens cameras are limited in their versatility, but are generally much less expensive than a camera body with several potentially expensive lenses. (The cost for interchangeable lenses can range from $1-200 for standard lenses to $10,000 or more for high quality, professional lenses.) In addition, fixed-lens cameras are typically smaller and easier to pack around on sightseeing or recreational trips. Those who wish to become involved in fine art, fashion, portrait, landscape, or wildlife photography, would be wise to become familiar with the various types of lenses serious photographers use. The following discussion is mostly about interchangeable-lens cameras. However, understanding the concepts will help in understanding fixed-lens cameras as well. Figures 1 & 2.

  • A Practical Guide to Panoramic Multispectral Imaging
    A PRACTICAL GUIDE TO PANORAMIC MULTISPECTRAL IMAGING By Antonino Cosentino 66 PANORAMIC MULTISPECTRAL IMAGING Panoramic Multispectral Imaging is a fast and mobile methodology to perform high resolution imaging (up to about 25 pixel/mm) with budget equipment and it is targeted to institutions or private professionals that cannot invest in costly dedicated equipment and/or need a mobile and lightweight setup. This method is based on panoramic photography that uses a panoramic head to precisely rotate a camera and shoot a sequence of images around the entrance pupil of the lens, eliminating parallax error. The proposed system is made of consumer level panoramic photography tools and can accommodate any imaging device, such as a modified digital camera, an InGaAs camera for infrared reflectography and a thermal camera for examination of historical architecture.

  • To Photographing the Planets, Stars, Nebulae, & Galaxies
    Astrophotography Primer Your FREE Guide to photographing the planets, stars, nebulae, & galaxies. eeBook.inddBook.indd 1 33/30/11/30/11 33:01:01 PPMM Astrophotography Primer Akira Fujii Everyone loves to look at pictures of the universe beyond our planet — Astronomy Picture of the Day (apod.nasa.gov) is one of the most popular websites ever. And many people have probably wondered what it would take to capture photos like that with their own cameras. The good news is that astrophotography can be incredibly easy and inexpensive. Even point-and- shoot cameras and cell phones can capture breathtaking skyscapes, as long as you pick appropriate subjects. On the other hand, astrophotography can also be incredibly demanding. Close-ups of tiny, faint nebulae, and galaxies require expensive equipment and lots of time, patience, and skill. Between those extremes, there’s a huge amount that you can do with a digital SLR or a simple webcam. The key to astrophotography is to have realistic expectations, and to pick subjects that are appropriate to your equipment — and vice versa. To help you do that, we’ve collected four articles from the 2010 issue of SkyWatch, Sky & Telescope’s annual magazine. Every issue of SkyWatch includes a how-to guide to astrophotography and visual observing as well as a summary of the year’s best astronomical events. You can order the latest issue at SkyandTelescope.com/skywatch. In the last analysis, astrophotography is an art form. It requires the same skills as regular photography: visualization, planning, framing, experimentation, and a bit of luck.

  • Choosing a Lens of the Right Focal Length That You Will Get the Appropriate Angle of View
    How to choose a camera lens Understanding the technology SUMMARY When you buy a camera, make sure the lens is suited for the intended purpose. With the right lens, you can greatly enhance the results you achieve in a particular type of photography and, by having a variety of lenses, you can greatly extend the usefulness of your camera. This paper provides a basic introduction to the principles of camera lenses. It explains the terminology: what is meant by focal length and f/number? Choose the right lens and taking good photographs becomes so much easier! The Basics The most important component of your camera is the lens. It’s no good having a camera with an impressively large number of megapixels if the lens is not up to the job. A lens has two basic properties: Focal length This determines the field of view of the lens. To match human vision, you’d need a lens with a focal length of about 35mm (in photography, focal length is always measured in millimetres). The normal, or standard, focal length for a camera lens is 50mm - anything smaller is called wide-angle, anything greater is called telephoto. A camera lens offering a range of focal lengths is called a zoom lens; one of fixed focal length is called a prime lens. f/number The ratio of the focal length of the lens (f) to its effective diameter: the size of its ‘window’ on the outside world , or aperture. The f/number is a measure of the light gathering power of the lens (called its speed).
