Analysis of Field Tests Comparing Second and Third Generation Image Intensifiers
Abstract
The photopic (foot-candle) measure and reporting of field test illumination conditions, as related to comparative testing of any nonphotopic sensor(such as GEN2 or GEN3 intensifier systems), have produced widespread misinterpretation of the test results and have promulgated a false presumption that the comparative tests were performed under the same conditions. A recent analysis of one of the field tests provided strong evidence that a predominance of artificial light from nearby areas contaminated the site. The effects of such contamination-not representative of a wartime blackout environment-were analyzed showing that GEN2 and GEN3 performance tended toward equality as the relative amount of artificial light contamination increased. Keywords include: GEN2 and GEN3 image intensifier systems; S/N ratio, Foot-candle, Lux, Photocathode, Light level, Photometric, Photopic.
