Abstract In the double-CCD guidance device, planar array CCD, filter and video signal processing system are adopted. In the planar array CCD FOV range, there is a spectroscopic element to separate incident beam into two parts to a main optical path and a secondary optical path with a narrow band filter and a planar array CCD. In the two CCDs, two image with the same spatial position and different spectral characteristics are formed, and through optoelectronic conversion driven by a clock circuit, two video signals with the same time sequence and different content are output and subtracted in signal treating circuit to realize resisting interference of strong light.
