FPGA-Based Micro Fiber-Optic Spectrometer Hardware Circuit System

Abstract:

Portability has become an inevitable trend of spectrometer. Faced with the trend, one micro fiber-optic spectrometer hardware circuit system, which regarded XC3S250E as master chip to control CCD scan, A/D conversion and USB data transmission, etc, was designed, and the corresponding circuits were designed. After consecutive spectral scan test, we can find that the designed spectrometer is able to complete the acquisition, conversion and transmission of spectrum. The system stability is very good and the scanning accuracy can reach 1nm.
