基于FPGA的激光光束自对准电气自动化系统设计

摘要

激光光束技术运用的越来越广泛,包括光通信技术,激光测距技术,激光瞄准技术等,其中光通信技术范围最广;在光通信过程中,需要面对光束发射端与接收端中心对齐的问题,增加了操作的难度;针对光通信激光光束对准难的特点,研究并设计了一套基于FPGA的激光光束对准系统,利用在FPGA芯片上设计软硬件速度快、稳定可靠、研发周期短等特点;整个系统以FPGA芯片为核心,辅以操作电路、自适应算法;实验表明,该系统较好地符合了光束对准的要求.%Laser beam technology is used more and more widely,including optical communication technology,laser ranging technology,laser aiming technology,etc.the optical communication technology is the most widely used.In the process of optical communication,it is necessary to face the problem of the alignment between the transmitter and the receiver.Optical communication based on laser beam alignment difficult characteristics,research and design a set of laser beam alignment system based on FPGA,the design of hardware and software in the FPGA chip,high speed,stable and reliable,the characteristics of the short development cycle.The whole system takes FPGA chip as the core,supplemented by operating circuit and adaptive algorithm.The experimental results show that the system meets the requirements of beam alignment.
