摘要

为了满足航空光电吊舱多路Cameralink数字图像传输的需要，设计了以可编程逻辑器件（FPGA）作为核心处理器的多路Cameralink数字图像光纤传输系统。利用编解码芯片完成了Cameralink数字图像输入输出的信号转换。设计了异步FIFO数据缓存模块，解决了像素时钟域与Aurora协议用户时钟域的匹配问题。采用Aurora 8 B/10 B协议进行图像数据的编码、转换，结合高性能的波分复用光模块完成多路数字图像的传输。实验结果表明，数字图像数据传输的误码率低于10

-12

，图像传输效果清晰稳定。能够应用于多路Cameralink数字图像的传输。

Abstract

In order to meet the needs of multi-channel Cameralink digital image transmission in aeronautical photoelectric pod

a multi-channel Cameralink digital image optical fiber transmission system with programmable logic device (FPGA) as the core processor is designed. The signal conversion of Cameralink digital image input and output is completed by using codec chip; the asynchronous FIFO data buffer module is designed to solve the matching problem between camera clock domain and Aurora protocol user clock domain; the image data is encoded and converted by using Aurora 8 B/10 B protocol

and the multi-channel digital image transmission is completed by combining with high performance wavelength division multiplexing optical module. The experimental results show that the error rate of digital image data transmission is less than 10

-12

and the image transmission effect is clear and stable. It can be applied to multi-channel cameralink digital image transmission.
