Design on Multi-channel Signal Synchronous Detecting method

This paper presents a design plan of multi-channel infrared signal´s synchronous detecting. In order to improve system´s dependability, and to solve the problems such as big area, diversiform components, complex circuit and imprecise synchronization, Author adopted the hardware programmable technology (FPGA). System have the property below: numerous detecting channel, good synchronization, brief circuit, low price, and so on. In the end, through applying in the reality, result presents that performance of the system is stable and extensible, which can be used in the field of not only analyzing the object´s infrared property but searching the gathering and disposal of infrared image.
