基于单片机的激光图案投射仪中的接口电路

The Interface of Monolithic Computer Based Laser Projector

利用单片机对电机进行可逆调速，实现对激光束的调制，可获得一系列合成的激光图案．介绍了基于８０３１单片机的激光图案投射仪的整机结构、工作原理及供电电路，着重阐述了其接口的原理及电路实现。

Through reversible rotational speed regulation on motors controlled by 8031 monolithic computer, the laser beam modulation can be realized . Furthermore, a series of composite laser patterns can be obtained and observed. The structure, working principles and power supply of a laser projector based on 8031 monolithic computer are introduced. The principle and circuit of the interface are described in detail. In addition, a demonstration program to get a pair of synchronizing signals is proposed.
