The image acquired from synthetic aperture radar is a holographic image. It is transformed into visible light image through optical correlator.The content discussed in this paper is a device which transforms the light image information and displays it on common monitor. It consists of three parts: optic system array CCD camera and frame storage & real-time display system. The light is imaged on array CCD image pixels through optic system and transferred into electronical signal. This signal then is changed into video signal by frame storage & display system and real-time displayed on monitor. Different modes of displaying image are controlled by microcomputer.
