摘要
在自由空间激光通信系统中,通信双方对对方目标的捕获、对准、跟踪(APT)是通信过程中的重要环节。针对粗跟踪子系统的特点和要求,研制了光端机粗跟踪相机,从而实现对信标激光的捕获。该相机使用TC237B面阵CCD,可根据串口命令实时调节光积分时间、内部增益倍数、图像亮度偏置等参数,采用高速Camera Link数字输出接口。还具有根据命令选择驱动方式的功能,开窗口模式下输出256×256像元时帧频可达到100 f/s,满足粗跟踪伺服带宽的要求。
Acquisition, pointing and tracking are important processes in a free space laser communication system. For a coarse tracking subsystem, coarse tracking CCD camera was made to acquire the beacon laser. Optical integrated time, programable gain and image brightness offset are set in real-time by the series command in the array CCD TC237B. The digital image is output through Camera Link interface. The camera can choose its driving mode by the command. When the region-of-interest (ROI) drive timing with 256 ~ 256 pixel output is used, the frame rate can reach 100 frames per second and meet the servo bandwidth.
