Near-Infrared Spectrometer Optical Sensor Driving and Peripheral Circuit Design

Abstract:

In order to achieve Near-infrared spectrometer the feature of real-time capture and analysis in real time, CCD is used on the optical sensors. It has done a software simulation and hardware implementation.This paper presents the method of using VHDL for the solution of the linear CCD driving. Then, the external circuit is designed and the differential amplification processing to the output of the liner CCD is done in this paper. The results show that the system can correct drive,and the signal is displayed correctly. It needs only 2.5ms to complete a scany period in the 16MHZ crystal. The greater frequency of crystal,the shorter a scany period. The design is easy to understand. It has a great space to the behind application.
