摘要

摘要: 研制了一个激光分束测速系统。它由一台4mW He-Ne激光器，一个将单束激光分成10束相互平行的等间距（间距为5 mm）激光的分光器，一个高灵敏度、工作状态自检、可进行波形合成、10路接受、一路输出的光电接收转换装置，一台数字存贮示波器，以及微型计算机组成。可进行弹性撞击速度的测量。

Abstract: We designed and developed an element, which can split a single laser beam produced by a He-Ne laser device of 4 mV power into ten paralleled laser beams with an equal space-distance of 5 mm between each beam pair. We have developed a photo-electric transformer, which is of high sensitivity, waveform synthesized and has a single output channel. When combined with the digital oscilloscope and personal computer, we have the system can be used to measure the impacting velocity of the projectile launched by a gas gun.
