Available in PDF, EPUB and Kindle. Book excerpt: An interferometric acousto-optic spectrum analyzer system is configured in which the light signal is made proportional to the amplitude of the RF signal, thereby doubling the dynamic range in dB over the Bragg cell spectrum analyzer. In an experimental system a 40% increase in dynamic range was observed. Several schemes to generate a reference beam and obtain constant frequency interference beats are discussed. The theoretical and experimental dynamic range of noninterferometric and interferometric acousto-optic Bragg cell spectrum analyzers are determined. Experimentally, we have observed 58 dB dynamic range for a cw signal and 54 dB dynamic range for a 5 micro sec pulse signal. A short pulse of 60 ns length was detected with 20 dB dynamic range, 100% probability of intercept and less than 1 micro sec time-of-arrival accuracy. The system bandwidth was close to 250 MHz with 3.5 MHz frequency resolution. The spuriour level was below 50 dB. The system used a 5 mW HeNe laser in a Mach-Zehnder configuration. Discrete Si photodetectors with a fiber optic array were used in the experiment.

This book was released on 2012-12-06 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 34 (thesis year 1989) a total of 13,377 theses titles from 26 Canadian and 184 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 34 reports theses submitted in 1989, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Download or read book Interferogram Analysis For Optical Testing written by Zacarias Malacara and published by CRC Press. This book was released on 2018-10-03 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this day of digitalization, you can work within the technology of optics without having to fully understand the science behind it. However, for those who wish to master the science, rather than merely be its servant, it's essential to learn the nuances, such as those involved with studying fringe patterns produced by optical testing interferometers. When Interferogram Analysis for Optical Testing originally came to print, it filled the need for an authoritative reference on this aspect of fringe analysis. That it was also exceptionally current and highly accessible made its arrival even more relevant. Of course, any book on something as cutting edge as interferogram analysis, no matter how insightful, isn't going to stay relevant forever. The second edition of Interferogram Analysis for Optical Testing is designed to meet the needs of all those involved or wanting to become involved in this area of advanced optical engineering. For those new to the science, it provides the necessary fundamentals, including basic computational methods for studying fringe patterns. For those with deeper experience, it fills in the gaps and adds the information necessary to complete and update one's education. Written by the most experienced researchers in optical testing, this text discusses classical and innovative fringe analysis, principles of Fourier theory, digital image filtering, phase detection algorithms, and aspheric wavelength testing. It also explains how to assess wavefront deformation by calculating slope and local average curvature.

Book excerpt: An interferometric spectrum analyzer technique, using a distributed local oscillator, doubles the dyamic range of a conventional power spectrum analyzer (i.e., 60 dB vs. 30 dB), has an instantaneous analysis bandwidth of 200-1000 MHz, and is immune to scattered noise. An analysis of Bragg cell diffraction patterns shows that acoustic spreading leads to a curvature of the diffraction pattern along an elliptical or parabolic loci. Bounds on the size of integrating photodetector along the curved direction have been established based on frequency resolution criterion. This activity was extended to correct the acoustic spreading by using a holographic element. For a 12-channel Bragg cell operating over an 80 MHz bandwidth, the usable aperture was increased from 10% to 100%; the number of channels increased by a factor of four. An adaptive optical processing technique has been developed to overcome the bandwidth limitations of digital systems. These Bragg cells, used in an interferometer, provide the signal to be convolved as well as the tap weights. Extensive computer simulations of the performance of the system, given the finite integration times imposed by the Bragg cells, show that notch depths of 30-40 dB can be achieved for a system having at time-bandwidth product of 2000.

Available in PDF, EPUB and Kindle. Book excerpt: Optoelectronics is a rapidly expanding field of research and development. In years to come, it is destined to play a primary role in the growing information industry. The basic philosophy behind the science and technology of optoelectronics is to create and develop photonic devices in which optical photons (light waves) instead of electronic carriers, are manipulated for the conventional task performed by microelectronics. Thanks to the availability of large bandwidth at optical frequencies, the development of cost-effective low-loss low-dispersion silica fibers for optical transmission, and the possibility of ultra-fast two-dimensional processing, the field of present-day microelectronics is moving steadily towards this new technology of optoelectronics and photonics.This volume presents reviews of different areas of optoelectronics written by international experts in the field, covering most of the topics of recent importance. It includes detailed discussions on semiconductor lasers and optical amplifiers; optical fiber transmission; photodetectors; optoelectronic and photonic integrated circuits; light-wave telecommunications; optical signal and image processing; optical computing; nonlinear and integrated optics; space-time Fourier optics; optical metrology and sensing and optical interconnects. All chapters are written in the style of a textbook containing tutorial sections which should be of great use to graduate students. The volume should serve as an excellent book for graduate level course on optoelectronics, modern optical engineering, and optical communications.
