Digital method to checkout complete appliance of laser radiation indicating meter

According to the principle of laser terminal guidance, some important performances of laser radiation indicator are analyzed and the numeralization test method is introduced. Using simulation echo wave and accurate time delay circuit to measure ranging ability ,using CCD to grasp laser facular to measure divergence of laser pulse, the digitized methods are realized. It can measure the energy of every laser pulse, interval, frequency precision of one exposure period. It also gives the sequence chart to describe them. The circuit and light path diagrams are described with their data processing method. For using four-channel structure, host computer communicates with slave single chip microcomputer, the size of modularization is reduced, and the man-machine interface and the reliability of software are improved.
