An optical signal data acquisition and demodulation system is designed based on system on a programmable chip（SOPC）. Light spectrum acquisition, demodulation, FLASH real time storage and TCP/IP real time transmission are implemented using the field programmable gate array（FPGA） technology. The test results show that this system is stable, function complete, at the same time, the system also has advantages of high real-time, wide application, to be cut and easy to expand. In the field of laser measurement, photoelectric signal processing and so on, it has the application value widely.
