Paper Abstract

In this paper we present a laser imaging system based on the flying spot scanner concept associated with a computer image processing system of relatively high resolution. The horizontal and vertical deflection of the laser beam is realized by a pair of galvanometers guiding two perpendicular axis oscillating mirrors. A programmable electronic deviation system commands the galvanometers. The reflected laser light from the scene is detected by a high gain photomultiplier improving the signal to noise ratio. Because the total power of the laser beam is used, such a system is able to act with very low light power. Also it gives a large depth of view and offers zoom facilities. Its association with an image frame buffer and processing system offers other advantages such a good resolution and image enhancement. The whole is connected to a host computer for control and processing tasks.
