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2min,精度可达到4.17μrad,并具有集成度高、操作友好、可移植性强等特点。
In order to realize fast automatic alignment of optical path, reduce the error of manual adjustment of optical path and effectively improve the real-time and friendly operation of human-computer interaction interface, a set of visualized optical path automatic alignment system is designed. With the help of VC ++ programming technology, we carried out the secondary development on the image acquisition module of Victoria MV-U2000, and realized the collection, real-time display and saving of laser spot image information. Computer and lower computer STM32 serial communication, step by step control of the stepper motor to achieve a fast adjustment of the optical path, and to achieve the alignment. Experiments show that the optical path automatic alignment system can meet the application requirements of collimation. The single operation takes only 2min and the accuracy can reach 4.17μrad, and has the advantages of high integration, friendly operation and strong portability.
