Abstract

According to the spectral distribution of a laser illuminator and the reflectivity of the objects, the reflective spectral distributions of dark green paint, rough concrete, and green vegetation under laser radiation are deduced for a low-light-level night-vision system with a laser illuminator. The spectral-matching factors of Super S 25 and New S 25 photocathodes for dark green paint, rough concrete, and green vegetation are calculated and compared. The results show that the evaluation of visual range for a night-vision system with a laser illuminator under field circumstances is greatly influenced by the spectral-matching factor.
