Abstract

In compliance with the characteristics of the reference interference system in the Fourier transform infrared spectrometer, the paper puts forward a FPGA-based data acquisition system for the signal sampling of laser interference. This system adopts SRAM as the memory and the serial port transmission technology. Under control of FPGA, data of the interference signal are successfully acquired, stored and transmitted with finite state machine as the timing control mode. The acquired interference signal of laser shows that the data acquisition system is effective.
