Book Synopsis The Optical Transfer Function of Imaging Systems by : Thomas Williams
Download or read book The Optical Transfer Function of Imaging Systems written by Thomas Williams and published by CRC Press. This book was released on 1998-12-23 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Optical Transfer Function of Imaging Systems deals extensively with the theoretical concept of the optical transfer function (OTF), its measurement, and application to imaging devices. The OTF is a mathematical entity describing how well the subject is transferred into an image via the lens. The book focuses on the practical aspects of using and measuring the OTF. It presents the background physics necessary to understand and assess the performance of the great proliferation of electro-optical systems, including image intensifiers, video cameras, and thermal imagers. Assuming a senior undergraduate level of optics knowledge, the book is suitable for graduate courses in optics, electro-optics, and photographic science. In addition, it is a practical guide for systems designers who require a means of assessing and specifying the performance of imaging systems. It is also of interest to physicists and engineers working in all areas of imaging.
Book Synopsis Foundations of Optical System Analysis and Design by : Lakshminarayan Hazra
Download or read book Foundations of Optical System Analysis and Design written by Lakshminarayan Hazra and published by CRC Press. This book was released on 2022-02-06 with total page 775 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the incorporation of scientific approach in tackling problems of optical instrumentation, analysis and design of optical systems constitute a core area of optical engineering. A large number of software with varying level of scope and applicability is currently available to facilitate the task. However, possession of an optical design software, per se, is no guarantee for arriving at correct or optimal solutions. The validity and/or optimality of the solutions depend to a large extent on proper formulation of the problem, which calls for correct application of principles and theories of optical engineering. On a different note, development of proper experimental setups for investigations in the burgeoning field of optics and photonics calls for a good understanding of these principles and theories. With this backdrop in view, this book presents a holistic treatment of topics like paraxial analysis, aberration theory, Hamiltonian optics, ray-optical and wave-optical theories of image formation, Fourier optics, structural design, lens design optimization, global optimization etc. Proper stress is given on exposition of the foundations. The proposed book is designed to provide adequate material for ‘self-learning’ the subject. For practitioners in related fields, this book is a handy reference. Foundations of Optical System Analysis and Synthesis provides A holistic approach to lens system analysis and design with stress on foundations Basic knowledge of ray and wave optics for tackling problems of instrumental optics Proper explanation of approximations made at different stages Sufficient illustrations for facilitation of understanding Techniques for reducing the role of heuristics and empiricism in optical/lens design A sourcebook on chronological development of related topics across the globe This book is composed as a reference book for graduate students, researchers, faculty, scientists and technologists in R & D centres and industry, in pursuance of their understanding of related topics and concepts during problem solving in the broad areas of optical, electro-optical and photonic system analysis and design.

Book Synopsis Determining the Modulation Transfer Function of a Lens-film Combination Using the Diffraction Effects of a Coherent Imaging System by : Mark E. Washburn
Download or read book Determining the Modulation Transfer Function of a Lens-film Combination Using the Diffraction Effects of a Coherent Imaging System written by Mark E. Washburn and published by . This book was released on 1979 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This study will present a simple, quick, and inexpensive way to producing sinusoidal test targets, which can then be used in measuring the image quality of a photographic system by way of a coherent system. The sinusoidal test targets will be produced from a series of bar targets using Fourier Optics, and a comparison study will be made between measuring MTF with a laser and a microdensitometer. A defocused target series will also be produced to note the change in MTF of the photographic system. The results indicate that sinusoidal test targets can be made quickly and inexpensively, and then can be used to provide meaningful data in evaluating a system. It was found that the laser method used in measuring the MTF of a photographic system was found to be superior to the microdensitometer in convenience, in speed, and in noise reduction. However, the microdensitometer can perform tests which the laser cannot, which still makes the microdensitometer an essential and invaluable tool in measuring the image quality of a system."--Abstract.

Book Synopsis The Wavelength Dependence of the Modulation Transfer Function of the Atmosphere by :
Download or read book The Wavelength Dependence of the Modulation Transfer Function of the Atmosphere written by and published by . This book was released on 1972 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An apparatus was designed and constructed to measure the modulation transfer function of the atmospheric medium as a function of wavelength of light. The modulation transfer function (MTF) in this case was considered to be the ratio of the modulation of an optical target at a fixed range to the modulation at a range short enough so that atmospheric attenuation was negligible. Modulation measurements were made using a telescope which focused the image of the target on a slit. The image was mechanically scanned across the slit by a rotating mirror, and the intensity at the slit was measured by a photodetector. The preliminary results indicated a linear decrease in modulation of 0.1 per 1000A. (Author).

Download or read book Optical Transfer Function Measurement Intercomparison written by and published by . This book was released on 1988 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The optical transfer function (OTF) of a lens is used widely as an indicator for the quality in reproduction of images for both individual optical lenses and larger optical and electro-optical systems. The report is the synthesis of the outcome of an international intercomparison of the measurement of the optical transfer function. Of the four laboratories taking part in the exercise, two employed image scanning instruments in their measurements whereas the other two used interferometers. It is concluded that the intercomparison has demonstrated the capability of the participating laboratories to make equivalent measurement, within their uncertainties of measurement. The exercise has identified some sources of error for two of the laboratories. On this background some modifications of equipment and software have been undertaken. It has been confirmed that the scanning and interferometric techniques can produce equivalent results, with equal accuracy."--Editor.
