A Dual Channel Infrared Scanner for Atmospheric Imaging Studies at 10.6 Microns

Abstract

Abstract : A dual channel infrared scanning, display, and recording system originally developed for experiments in atmospheric imaging and image restoration at 10.6 microns has been modified for use with extended targets. Two image formats are now available, one providing two spatially separable images having 40 x 40 element resolution at 200 frames per second and the other, two images having 64 x 64 element resolution at 60 frames per second which may be joined, if desired, to scan a single rectangular image. Visual CRT displays of the infrared images are provided and magnetic tape recordings are made which may be played back later at recording speed or at reduced speed for viewing and to provide computer input for data analysis. This report describes in detail the modifications made to the scanning, display, and recording system and, together with the original report published previously, provides complete documentation for the system. A separate playback, display, and computer interface system, compatible with the scanner system, to be used for image restoration processing has also been developed. Both systems are to be delivered to RADC for infrared imaging and image restoration studies.
