The principle,architecture and feature of multi-module splicing long linear infrared dual-band image transmission system have been discussed.Aiming at the application requirement of infrared imaging detecting system,a new method for infrared dual-band image transmission has been proposed based on FPGA,which is also realized by using Aurora 8B/10B and PCI Express(PCI-E)protocols.The experimental results indicate that the system can be used to transmitting the infrared dual-band real-time image reliably,which...
