摘　　要：针对星间激光通信中光斑实时检测与跟踪需求,设计了一套基于Cameralink的图像采集、传输与显示系统。可编程逻辑器件(FPGA)接收Cameralink接口图像数据并在片内RAM缓存后,由数据通用传输(GTP)完成无压缩并行图像数据至高速串行数据的转换,然后经单模光纤实现至上位机的实时传输。对系统架构、收发端的软硬件设计进行了详细阐述。实验表明,在2.5 Gb/s链路传输速率下,系统可实现图像数据的准确解析与稳定传输,且具有抗电磁干扰能力强等优点,满足工程项目应用需要。For the demand of the real-time detection and tacking of the spot in space laser communications, a image acquisition, transmission and display system was designed based Cameralink protocol. By using the programmable logic devices, the image data was received through Cameralink protocol and cached in on-chip RAM ,then it was serial conversion high speed without compression. The data was transmitted to the host computer by a single mode fiber. The system architecture, transceiver hardware and software design et al. were discussed in detail. A experiment system was set up, and the experimental results show when the system will operate at a rate up 2.5 Gb/s ,the image was accurately decoding and stable, reliable transmitted. The advantages of this system is high bandwidth, high quality images and high anti-jamming level. It meets the needs of the project application.
