Abstract

Effect of increase in equivalent background illumination (EBI) with temperature of secondgeneration (18 mm) proximity focused image intensifier tube on the range performance of apassive night sight has been studied using the image intensifier minimum resolvable contrastmodel. It has been shown that for ambient temperatures of 40 oC and above, the range performanceof sight goes down drastically under low-illumination level due to increase in the EBI.Deterioration in range performance is negligible when ambient illumination is relatively high asin case of clear-starlit condition.
