Interferometric Spectrum Data Processing And Analysis System Based On LabVIEW

With the rapid development of modern science and technology,the data obtained by the spectrometer can be used to analyze the atmospheric temperature and humidity landmark composition and atmospheric pressure.Because the interference data obtained by the interference spectrometer cannot be directly converted into spectral data,this article has fully integrated the virtual instrument graphical programming technology and embedded technology,and digs into the advantages of both,using adaptive filtering algorithms and Fourier transform algorithm and phase correction,the built-up spectral signal acquisition and processing system can convert interference data into spectral data,and design a scientific information instrument integrating spectral signal acquisition and processing.This system uses the micro fiber optic spectrometer of the American Ocean Company as the relevant hardware equipment for signal information acquisition,and realizes the efficient processing and optimization of data through the effective design and application of the embedded microcontroller.The virtual instrument LabVIEW is used to read and segment the interference data,process the interference data,and obtain the required spectrum data through data inversion.It is actually applied to the different wavelength responses of the calibration spectrum on the spectrometer to test the operation effect of the spectrum analysis system.The experimental results show that the spectrum analysis system designed in this paper can obtain the collected mercury cadmium telluride detector(MCT)data spectrum and antimony The indium sulphide detector(INSB)data spectrum band can better complete the spectrum analysis work.
