Design of Dual Channel Small Signal Detection in Infrared Spectrometer

SHI Yang,LIU Hui-jun,LJin(College of Metrology Technology and Engineering,China Jiliang University,Hangzhou 310018,China)  
A design of small signal detection in infrared spectrometer with dual channel structure is presented.The jamming caused by the fluctuation of the light source as well as the shift of optical intensity modulating frequency are barraged.The SNR of the detection system is improved.
