Research on Airborne Near Infrared Spectroscopy Equipment

After the experiment at near darkroom conditions, using sodium light through the iris diaphragm to the Fourier spectrometer, the spectrometer is completed by adjusting the interference of sodium, Fourier transform, the peak value of the interference, is received by the detector to the computer. After the image acquisition software acquisition and storage, and then the error analysis and processing, in order to verify the measurement accuracy of the spectrometer can reach 1nm.During the experiment, in order to weaken the influence of stray light on the measurement of the interferogram, and the SNR, we used a black box approach, on the black cloth covered multilayer experimental platform, the stray light offset further validate the reliability of the experimental system.
