Design of Laser Positioning System Based on Photoelectric Detector

光学测量定位在光电技术领域中具有重要地位,同时也被广泛应用于各个领域。光电探测器是测量的核心器件。通过激光定位进行测距,对比各种光电探测器件最后选择PSD,提出了基于PSD和STM32的激光定位系统。以激光三角法为基础通过PSD输出经过信号放大变换处理以后用STM32进行采集显示和计算,对被测物体进行定位。STM32是一款功能强大的单片机,完全满足本系统设计需要。设计了简易的定位测量系统,并对该系统进行了测试,拥有高精度和低成本响应速度速度快等特点,具有一定的实用和研究价值。

Optical measurement positioning plays an important role in the field of optoelectronic technology,and is also widely applied in various fields.Photoelectric detector is the core device of measurement.In this paper,laser positioning was used to measure the distance.Compared with all kinds of photoelectric detectors,finally PSD was selected.A laser positioning system based on PSD and STM32 was proposed.Based on the laser triangulation method,after the PSD output being processed by signal amplification transformation,STM32 was used to collect,display and calculate,and locate the measured objects.STM32 was a powerful microcontroller,which fully meets the design requirements of the system.In this paper,a simple positioning system was designed,and the system had been tested.It has the characteristics of high precision and low cost response speed.It has some practical and research value.
