Since the free space optical communication has drawn people's extensive attention, the requirement of detecting the photoelectric signal and according data processing in industries and research areas has become increasingly strict. In this paper, for the purpose of achieving a high precision photoelectric data acquisition system design, author proposed that employing the FPGA chip EP2C5Q208C8 as master chip, cooperating TLC5510 to proceed multichannel synchronous A/D conversion in order to accomplish date col ection of the photoelectric signal. Through software and hardware programming, this system is able to effectively gather 8-channel, 8-bit photoelectric signal and consequently complete display function of the photoelectric signal detection and data col ection through FPGA computing and USB 2.0 communication.
