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 semiconductor light-emitting device is used as a target analog light source, and the laser pulse emitted by the receiving system or equipment is used to acquire the pulse synchronization signal of the emulation test, so as to start the delay process of the simulated target echo pulse, and delay back to the system under test or equipment feedback Three appropriate intensity analog echo (light) pulse, by measuring the response of the system under test, can determine whether the performance of the ranging meet the technical indicators. This technology integrates the laser energy detection, the extraction of pulse synchronization signal and the simulation echo of the target echo signal to realize the non-destructive indoor (online) simulation detection of the optical interface of the pulsed laser ranging system or equipment.
