应用电机可逆调速的激光图案投射仪
A Laser Projector Obtaining Composite Patterns Through Reversible Motor Rotational Speed Regulation
Abstract
介绍一种应用 8031 单片机的激光图案投射仪的整机结构和显图工作原理，通过对直流电动机的可逆调速获得合成的激光图案。同时给出产生一组几何图案所对应的两电机各自转向及端电压值。 This paper introduces the structure,working principles of a laser projector based on 8031 monolithic computer.Through regulating the rotational direction and speed of direct current motors,a series of composite laser patterns can be obtained and observed.In addition,it gives by experiment,the respective rotational directions and voltages of the two motors,corresponding to different geometrical patterns.
