Book Synopsis Improved Methods of Performing Coherent Optical Correlation by : Akram S. Husain-Abidi
Download or read book Improved Methods of Performing Coherent Optical Correlation written by Akram S. Husain-Abidi and published by . This book was released on 1972 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coherent optical correlators are described in which complex spatial filters are recorded by a quasi-Fourier transform method. The high-pass spatial filtering effects (due to the dynamic range of photographic films) normally encountered in Vander Lugt type complex filters are not present in this system. Experimental results for both transmittive as well as reflective objects are presented. Experiments are also performed by illuminating the object with diffused light. A correlator using paraboloidal mirror segments as the Fourier-transforming element is also described.

Download or read book Optics and Photonics written by National Research Council and published by National Academies Press. This book was released on 2013-03-19 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optics and photonics technologies are ubiquitous: they are responsible for the displays on smart phones and computing devices, optical fiber that carries the information in the internet, advanced precision manufacturing, enhanced defense capabilities, and a plethora of medical diagnostics tools. The opportunities arising from optics and photonics offer the potential for even greater societal impact in the next few decades, including solar power generation and new efficient lighting that could transform the nation's energy landscape and new optical capabilities that will be essential to support the continued exponential growth of the Internet. As described in the National Research Council report Optics and Photonics: Essential Technologies for our Nation, it is critical for the United States to take advantage of these emerging optical technologies for creating new industries and generating job growth. The report assesses the current state of optical science and engineering in the United States and abroad-including market trends, workforce needs, and the impact of photonics on the national economy. It identifies the technological opportunities that have arisen from recent advances in, and applications of, optical science and engineering. The report also calls for improved management of U.S. public and private research and development resources, emphasizing the need for public policy that encourages adoption of a portfolio approach to investing in the wide and diverse opportunities now available within photonics. Optics and Photonics: Essential Technologies for our Nation is a useful overview not only for policymakers, such as decision-makers at relevant Federal agencies on the current state of optics and photonics research and applications but also for individuals seeking a broad understanding of the fields of optics and photonics in many arenas.
Book Synopsis Image Matched Filter Correlator Experiments by : F. B. Rotz
Download or read book Image Matched Filter Correlator Experiments written by F. B. Rotz and published by . This book was released on 1976 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work described in this report is the continuation of the development of an automatic stereo compilation system based on coherent optical techniques. A breadboard coherent optical mapping system was modified to improve its accuracy and overall performance while at the same time simplifying the basic optics involved. Methods for preprocessing imagery to enhance correlation performance were studied and phase-type spatial filters were used to increase optical efficiency. The problem of data readout was investigated with particular attention to the use of an optical heterodyne technique. Computer and interface requirements for a fully automatic breadboard system were established and the use of real time filters was considered. Results indicate that this coherent optical system has considerable promise in the area of parallax measurement and, with slight modification, may be a useful tool for feature extraction from aerial photographs.
