An Adaptive Tunable Raman Spectrum Intensity Method Based on Digital and Analog AGC Control

摘要

This paper presents a auto control Raman spectrum intensity method based on auto adjust linear CCD integration time and analog amplifer gain control. Introduces a linear CCD timing sequence control signal generation and integration time auto control realization,and also present the linear CCD analoy signal output auto gain control curcuit and realization ,publishes this design key parts analog and digital circuit schematic,provides a most effective solution for hand held Raman spectrometer fast measurement and lower power consumption.
