为设计更具实用性的轻**射击训练激光模拟系统，解决现有系统弹着点坐标信号采集结构存在的不足。基于激光调制技术，提出阵列式多路调制激光信号采集的方法，设计了一种二极管线与方式的信号采集结构，使用横纵两条总线来确定一个弹着点的坐标，旨在实现实时精确报靶的同时降低系统复杂程度。并结合接收芯片的响应阈值使用滤光薄膜控制激光光斑的有效半径，解决普通激光器远距离处光斑过大的问题。

Existing small arms shooting training simulation system has the shortage of shot coordinate signal detection, In order to designing and solving this problem，the laser modulation technology and the multichannel data quick collection structure is introduced. The method of array multichannel modulation laser signals detection is put forward. A sort of diode string and signal detection structure is invented. The abscissa and ordinate is used to ensuring shooting coordinate, and the membrane is used for solving the problem of ordinary laser spot is too large in distance.
