Abstract:
A new scheme based on synchronous-scanning is presented.It uses the receiver to send synchronous optical pulse and achieve the timing synchronization between the sending and receiving sides.The paper introduces in detail the circuit structure of the system,and analyses the principle of light trigger synchronization and scanning identification of optical path.Thereafter the actual detection,the system can work reliably,and has begun to enter the industrial applications.
