摘要：
NIR spectrum signal is inundated with background noise signal produced by many factors. so the photoelectric detector and the filter can detect the useful signal. To solve the problem, this paper designed a new method-Lock-in Amplifier (LIA) bases on Correlation Detection, which is applied to NIR spcertrometer. This method can solve the problem of getting signal in NIR spectrometer.
