Study of Laser Beam Autocollimation System
摘要
为了实现光路的快速自动准直, 降低手动调整光路的误差, 有效提高人机交互界面操作的实时性和友好性, 设计了一套可视化的光路自动准直系统。借助VC++编程技术, 对维视MV-U2000图像采集模块进行了二次开发, 实现了激光光斑图像信息的采集、实时显示和保存。计算机与下位机STM32进行串口通讯, 通过控制步进电机自动调节步长实现了光路的快速调整, 并使其达到准直。实验表明, 该光路自动准直系统能够满足准直的应用需求, 单次操作只需2 min, 精度可达到4.17 μrad, 并具有集成度高、操作友好、可移植性强等特点。
Abstract
In order to realize rapid autocollimation of laser beam, decrease the error during manual adjustment of laser beam, and increase real-time performance and friendliness of man-machine interface operation, a visual autocollimation system for laser beam is designed. Secondary development of MV-U2000 image collecting module is carried out with the help of the VC++. The acquisition, real-time display and storage of the image of the laser spot are realized. Through the serial communication between the PC and the STM32, rapid adjustment of laser beam is realized by auto-adjusting the step size of stepper motor. Then, the laser beam collimation is achieved. The experiment results show that the autocollimation system satisfies the application requirement of collimation. The single operation lasts for 2 min and the measurement precision is up to 4.17 μrad. The system has the characteristics of high-integration, user-friendliness and high-transportability.
