Available in PDF, EPUB and Kindle. Book excerpt: Two point resolution criteria is the classic way of comparing telescopes. However, the standard two point resolution criterion is not appropriate for multi-aperture systems. This paper proposes a new two point resolution criterion based on the idea of thresholding the irradiances of the resulting far field diffraction patterns of multi-aperture optical systems. The threshold was defined as a fraction of the central lobe irradiance. The thresholds varied from 0.1 to 0.9 of the central lobe irradiance of the far field diffraction patterns. Theoretical data of normalized irradiance versus point separation for various multi-aperture optical systems were presented. The two point resolution for these configuration was analyzed. The two point resolution criterion using thresholds was demonstrated. The threshold criterion provided the information necessary to compare the two point resolution performance of a particular multi-aperture optical system illuminated coherently and incoherently. Also, this criterion allowed the comparison of the two point resolution performance of systems composed of three, four, and six subapertures illuminated incoherently. (Theses).

Available in PDF, EPUB and Kindle. Book excerpt: The imaging of simple objects through coherent multiple aperture optical imaging systems was investigated. Multiple aperture telescopes are a candidate technology for the Strategic Defense Initiative missions of surveillance, tracking, and kill assessment. In this thesis, the multiaperture images of edges, slits, rectangles, and circles were theoretically predicted and experimentally produced. Photographs of the actual images produced in the lab were compared to the theoretical images, and the analytical and computer prediction techniques were found to be accurate. All of the results were analyzed to determine how different multiaperture geometries affected the images. It was found that multiaperture geometries affected the images. It was found that multiaperture imaging produces edge enhancement. The position of a single edge could be found exactly, while multiple edges sometimes produced slight edge shifts. A computer program was developed tat predicts that edge shifts that will be observed when imaging through a given multiple aperture. Larger subaperture spacings were found to exhibit better resolution but produced more ringing about the edges. The possibility of rotating the multiple aperture system to gather more information was discussed, as well as designs that include a central subaperture.

This book was released on 2015-11-09 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The designers of optical systems must be able to treat the image quality in order to have parameters which they can control. The field of image quality analysis is concerned with the development of quantitative merit functions which can be used to calculate image quality in user terms from lens design parameters. The most two complete measures of image quality in user terms are the point spread function (PSF), which is the Fourier transform of complex pupil function, and the optical transfer function (OTF), which is the Fourier transform of PSF.

This book was released on 1987 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various multiple aperture optical arrays were compared while imaging objects illuminated with incoherent light. The aperture arrays contained from one to four sub-apertures. The objects were edges, slits, rectangles and circles. An emphasis was placed on edge resolution, and the author derived his own set of resolution criteria. Based on this analysis, a tight square four-element array was the best performer. The study concluded with an analysis of design criteria for optimum incoherent imaging resolution. Max sub-aperture size, min sub-aperture spacing, max number of sub-aperture elements, and a symmetric pattern were all determined to be desirable in order to obtain the best performance.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is presented as a tribute to "two icons from the world of optics"--in the words of editors Harvey (Center for Research and Education in Optics and Lasers, U. of Central Florida) and Hooker (electrical and computer and engineering, U. of Colorado)--both of whom have been affiliated with the Optical Sciences Center at the U. of Arizona. Twenty-one papers from a tribute conference, some highly technical and others more personal, detail the honorees contributions to optics and optics education. These are followed by 45 journal article reprints authored by Bob Shannon and Roland Shack or their students in the technical areas of optical design and analysis, image evaluation, applications of the marginal ray height--chief ray height diagram, optical testing, optical fabrication, phased telescope arrays, aberration theory, propagation effects in the atmosphere, and diffraction/surface scatter phenomena. Finally, 14 short, informal "anecdotes and accolades" of the two scientists are presented from the conference and elsewhere. Annotation :2005 Book News, Inc., Portland, OR (booknews.com).

Available in PDF, EPUB and Kindle. Book excerpt: Optical System Design covers the basic knowledge of optics and the flow of light through an optical system. This book is organized into 16 chapters that deal with various components of an optical system, from light and images to spectroscopic apparatus. The book first discusses the simple components of an optical system, including its light, lens, oblique beams, and photochemical aspects. It then deals with the system’s projection, plane mirrors, prisms, magnifying instruments, and telescope. Other components considered are the surveying instruments, mirror imaging systems, photographic optics, and spectroscopic apparatus. This book is of value to undergraduate students with courses in geometrical optics and system design.
