IMAGE LASER RADAR EQUIPMENT

PURPOSE:To display measurement result with the light and gray-scale image of an image by turning on the output of an image intensifier (II) tube only while its gain increases or decreases monotonously. CONSTITUTION:A sinusoidal wave generation circuit 41 generates a sinusoidal voltage and the output is given to amplifiers 43A and 43B via phase adjustment circuits 42A and 42B. A laser beam from a light source 2 is projected to a subject 1. The reflection light is reflected by a mirror 5 and enters an II tube 3. The output of the amplifier 43B, namely a sinusoidal voltage, is given to an photoelectric surface 31, thus modulating gain. The output of a gate amplification constant circuit 48 is given to a gate drive circuit 49 and the output is applied to a micro channel plate 34 for gate operation, thus turning on the output of the II tube only while the gain of the II tube 3 increases or decreases monotonously and hence displaying a close position brightly and a distant position with a dark in gray scale.
