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.
