摘要
利用半导体发光器件作为目标模拟光源,通过接收系统或装备发射的激光获取仿真测试的脉冲同步信号,以此信号启动模拟目标回波脉冲的延时过程,延时结束向被测系统或装备回送一至三个强度适当的模拟回波(光)脉冲,通过检验被测系统响应,可判断测距性能是否符合技术指标。这项技术将激光能量检测、脉冲同步信号的提取和目标回波信号的仿真回送集于一体,实现了脉冲激光测距系统或装备的光接口无损室内(在线)仿真检测。
The method of simulated test of pulse laser rangefinder uses LED (or LD) to simulate object to test pulse laser rangefinder (or ranging equipment). The test system receives a laser beam generated by rangefinder and starts a precision time delay. Then it feeds back an (one to three) 'object pulses' to the rangefinder tested and begins another time delay (twice) at the moment of the timing ends. Whether the rangefinder works normally by observing the display of the rangefinder and the laser energy the rangefinder emitted at the same time is measured. By this method, the online test of the pulse laser rangefinder becomes possible. \;
