Spectral matching technology of a low-light-level night-vision system with a laser illuminator.
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.
