Abstract


Fourier transform spectrometer with high-throughput , multi-channel , high-resolution , high wavenumber accuracy advantages , is a powerful tool for spectral analysis , can be used for a wide spectrum of the complex spectrum or very weak spectral measurement . Reference light generating timing pulses measured signal samples for the Fourier transform spectrometer movable mirror movement control , as well as the interference pattern data acquisition requirements of the three main aspects , the design and implementation of this article the measurement of a Fourier transform spectrometer data acquisition system . This overall design ideas as follows: two light source emits light through the interferometer becomes a reference interference pattern and the measured interference pattern , the optical signal is converted into an electrical signal by the photoelectric detection circuit , the reference signal has been processed by the beam folding method zero comparator circuit , the measured signal in DSP data acquisition system for real-time data acquisition and through the PCI riser card , the collected signals to the computer , using LabWindows / CVI signal Fourier transform spectrogram , so as to realize the accurate calculation of the spectral resolution . This paper details the control interferometer moving mirror moves motion control system , interference Figure photoelectric sensing unit to receive treatment and zero-crossing comparator circuit , self-developed multi-channel the DSP data collection system , virtual instrument LabWindows / CVI software to prepare monitoring and control and data acquisition system as well as experimental results . Fourier transform spectrometer measurements of the hardware and software of the data acquisition system designed to meet the characteristics of the virtual instrument . A self-developed DSP data acquisition system using DSP as the CPU main from two distributed high - speed , high-precision real - time multi-channel analog signal acquisition and processing system . Preparation of PC software virtual instrument LabWindows / CVI language , it has a short development cycle , the use of more flexible , powerful functionality , FTS system is more suitable for the collection of the interference signal , windowing , fast Fourier transform signal processing methods of demand , thus improving the measurement system the interferogram data acquisition , analysis and processing power . Fourier transform spectroscopy measurement data acquisition system designed in this paper , accurate data transmission to meet the design requirements , and has a friendly interface , scalability characteristics .
