为提高光电跟踪设备图像传输的带宽,提高其抗干扰能力和减少配线工作量,提出一种光纤传输系统的设计方案. 针对cameralink接口的相机,对并行图像数据进行主控处理、编码串行化,通过光纤传输后在接收端再进行解码、主控处理后完成采集. 在方案中,加入自诊断机制初步判断光纤通信链路是否通信正常. 实验结果表明,此方案对于cameralink相机具有通用性,可实现光纤通信链路的自诊断,并且实现了base配置模式和medium配置模式下的图像传输. 传输无误码,单通道传输带宽最高可达2 Gbps.

In order to enhance the bandwidth and the anti-jamming capacity of an optic-electronic tracker, a fiber communication system used for cameralink cameras was designed. The parallel data were serialized after they were processed in FPGA and transferred to the receiver by fiber.The receiver decoded serialized data to parallel data and sent them to frame grabber. A self-test function was used to verify whether communication is normal. The experimental results show that its self-test-function works normally, it transfers images in the base and medium configurations without errors, and the maximum bandwidth is 2 Gbps in a single channel.
Key words： fiber; camerlink; self-test; medium configuration
