| 摘 要： | 系统通过选取半导体激光器作为光源、大面积光敏二极管作为接收器件。采用通过柱面透镜和圆弧柱面反射镜形成的激光幕作为区截面。整个装置由两套相同的激光光幕构成，用以获取弹刃通过两个光幕的时间间隔。通过接口电路，根据靶距由计算机进行数据处理，得到弹丸的飞行速度。该系统具有效靶区大，灵敏度高，响应速度快，抗干扰能力强，测速范围广等特点。

| Abstract: | The laser system of measuring velocity selects appropriate semiconductor laser device as Light source and a large area photoallergy diode as receiver, use the laser curtain formed by arc cylindrical mirror as section. The system composes of two kind of laser curtain to obtain the time interval of passed bullet. The velocity of bullet is calculated by computer according to the distance of two target.. The system has advantage of higher sensitivity, large effective area, high response speed., powerful ability of resisting interference and wide scope of measuring velocity. |
