激光扫描技术在靶场测试中的应用研究

为了解决光电类仪器在武器射击准确度和射击密集度的测试中遇到天空背景亮度不够,或弹丸口径小,弹道偏高而无法测试的问题,利用旋转棱镜使激光束在空中扫描,照亮弹丸表面,从而大大降低对光电传感器灵敏度的要求,使得该项测试工作不受天空背景条件的影响,并提高测试精度.

MEASUREMENT IN SHOOT RANGE WITH LASER SCANNING TECHNIQUE

In most of the optronical instruments of shooting range,there are some problems of accuracy and precision of fire in the measurement that the ambient doesn’t meet the requirements such as the low luminance of background or the bullets size,even the trajectory changes.The requirement of transducer’s sensitivity can be decreased by means of a rotating prism that makes the laser beam scanning the space and illumining the bullets’surface.These methods make the test job free from the influence of the space background and increase the accuracy of measurement.
