摘要
随着测量技术的发展,光通信定位技术的应用也日益广泛。为了有效提高激光定位的精度,文中基于PPM调制技术对现有的激光定位系统进行了理论上的改进,并利用光斑阈值控制单元对目标返回的激光脉冲进行了背景光和能量较弱区域的滤除,从而进一步锁定目标的中心位置。
With the development of measurement technology,the application of optical communication positioning technology has become increasingly widespread. In order to improve the accuracy of the laser positioning,this paper aims to theoretically improve the existing laser positioning system based on PPM modulation technology,and using the beam spot threshold control unit for filtering out the background light and weak energy region of the target returning laser pulses,locking the center of the target.
