ABSTRACT:
The light output of pyrotechnic luminants under dynamic conditions can be nitored to obtain data representative of ground surface illumination as a function of time and position of the illumination source. An array of photocells is disposed at substantially ground level throughout the range testing area, these photocells being sequentially scanned to provide a serial electrical data output during the firing of a pyrotechnic luminant-containing projectile over the range testing area. The serial data is transmitted to a remote control location whereat the data is received, sequentially demodulated, and converted into an optical display synchronously with the scanning in a pattern which simulates the illumination impinging on the photocell array. The position of the projectile over the range testing area is simultaneously tracked and a tracking information display is also provided. The illumination display pattern is recorded in correlation with the tracking information display so as to provide a frame-by-frame record of the ground surface illumination of the luminant as a function of time and the position of the illumination source.
