Until the appearance of the sniperscope, a soldier in the field was severely restricted in nighttime surveillance. Since that time, other devices known as image intensifiers have appeared. Although similar in some respects, use of the image intensifier differs from that of the sniperscope in certain basic respects, particularly in that it can function with only the illumination of the night sky. The object of this study is to determine whether new criteria for personal camouflage exist as the result of the emergence of the image intensifier. Topics considered include spectral energy distribution of radiation from the night sky, spectral sensitivity functions of typical detectors, reflectance characteristics of the terrain, and the geometric conditions of viewing a scene with the image intensifier. The analysis leads to the conclusion that ideal camouflage against the image intensifier requires reflectance values somewhat higher than those adopted with respect to the sniperscope.
