| Summary |
Advancing technology in detector arrays, flat panel displays, and digital image processing provides new opportunities to expand imaging applications and enhance system performance. Technical managers and design engineers are faced with evaluating the cost, weight, and performance of an ever-expanding selection of technology options. This tutorial text provides the theory, procedures, and information necessary to evaluate and compare the performance of available imaging technologies. Part I updates the earlier work presented in Analysis of Sampled Imaging Systems (2000). Part II discusses performance evaluation of electro-optical imagers. Part III provides computer programs (on a supplemental CD-ROM) and up-to-date information on detector arrays, optics, and display options |
