  • A video system with a transmission speed of 622 Mbps is designed and realized by taking the high speed characteristic of wireless laser communication. Functions of the system such as video converting, data processing and buffering, laser transmitting/receiving are implemented on a single circuit board to achieve a better flexibility. The ping-pong operation which is made up of internal asynchronous FIFO(First in First out) is utilized to effectively switch the continuous video data flow. Manchester code is employed to obtain better recoveries of data and clocks from the received signals. Moreover, it is also easier to detect the byte boundary from serialized data flow and to synchronize the communication. Experimental results show that the system can transmit video signals stably and meet the application need in the under ground distance, and the system provides a platform for further research on laser communication technologies.
