Abstract

An infrared system for measuring the spatial, temporal and low resolution spectral distributions of radiating sources is described. The system has three main subassemblies: a Data Acquisition subsystem consisting of a selectively filtered spatially scanning IR camera; a Display and Preprocessing subsystem; and a Digital Video Process subsystem. Unique features of the system include data display components which provide grey scale, two configurations of pseudo-color, and 3-D graphical displays, a video digitizing interface, and an interim storage facility. The system can be operated in a real-time or delayed playback mode. The IR Scanner camera (AGA System 680 Thermovision) provides 16 frames per second of an optional 10 X 10 or 2 X 2 fields-of-view, with 1.3 or .3 millirad instantaneous fields-of-view, respectively. Spectral content is obtained by changing discrete bandpass filters. System characteristics, atmospheric attenuation corrections and calibration procedures for direct source radiance determination from pseudo-color displays are given.
