一种新的红外焦平面图像信号无线光输出协议

文中提出了一种针对红外焦平面图像信号无线光输出的高速数据链路层协议。该协议以IrDA标准的红外数据链路协议(IrLAP)作为参考，通过红外无线信道来实现点对点、高速、稳定的图像信号输出。协议的设计充分考虑了对多种红外传输速率的支持，以及位错误率(BER)、红外帧长度、应答分组大小等因素对系统传输吞吐量的影响，提出了寻找合适参数有效的计算方法，以及基于FPGA的红外无线视频传输平台的设计方法。实验结果显示，传输平台可以在16Mb／s的红外传输速率下长期稳定工作。这表明本协议适用于VFIR及更高速率的图像无线传输，经过不断地测试与完善，可为制订今后焦平面图像信号光输出规范提供参考。

A Novel Wireless Optical Transport Protocol for Infrared Focal Plane Array Image Output

A high speed data link layer protocol of wireless optical transport is proposed on the basis of standard IrDA Link Access Protocol (IrLAP) for infrared focal plane array (IRFPA) image data output. This protocol makes use of the infrared wireless channel to realize the point to point,high speed and stable image data transport. With the multi speed support of the infrared transmission,the protocol also takes the influence of Bit Error Rate (BER),frame length and window size into full account. Then equations about how to calculate the optimal parameters are presented to maximize the data throughput at a certain BER. An infrared wireless video transport platform based on FPGA is also given,which can work stably at the transmission rate of 16Mb/s for a long time. The experiment results show that the protocol is suitable for the image transporting at VFIR and higher rates. Through continuous development and consummation,this protocol is potential for the optical transport criterion of the IRFPA image data output in the future.
