“…It has been widely applied in various fields such as food 3,4 , astronomy 5 , agronomy 6,7 , medicine and health 8 , and so on 9 . Traditional spectrometer usually includes scanning monochromators and photomultiplier tubes 10 , which has deficiencies such as large size, complex structure, expensive price, and restricted use environment, and cannot be universally applied [11][12][13] . Compared with the traditional spectrometer, the miniature spectrometer is small in size, simple in structure, easy to measure, and has good secondary development 14 Therefore, the miniaturization of spectrometer has become an important direction for the development of spectrometer at present 15 .…”

In order to meet the demand for portable use of the spectrometer and improve the spectral acquisition rate, the driving circuit of the miniature fiber optic spectrometer was designed. The system uses Ibsen Photonic's FSV-101 miniature fiber optic spectrometer, which integrates the S11639-01 high sensitivity Complementary Metal-Oxide Semiconductor (CMOS) image sensor. The main control chip is Field-Programmable Gate Array (FPGA), and the analog-to-digital conversion of the CMOS output signal is performed by A/D conversion chip. The system uses FPGA to drive the CMOS timing and A/D conversion timing, and then communicates with the host computer through the serial port, transmits the spectral data to the host computer for dynamic display of the spectrum. In order to verify the overall performance of the system, laser light sources were used to conduct spectral acquisition experiments. The experimental results show that the system accurately outputs the spectral data of the light source, the spectral acquisition range is 200-1000nm, the frame rate is 111Hz, and the acquisition accuracy is 8bit, which has good practicability.
