Design And Development Of Static Spectrum Acquisition And Processing Software

With the development of spectroscopic techniques,computer science,qualitative analysis of the current quantitative substance,pollutant gas composition testing,laser spectral calibration,etc.,it has new requirements.In order to improve spectral resolution capability of the system and improve the stability of the test system,new spectroscopic analysis systems and software are endless for enhanced system compatibility and data portability.In discussed the basis of various interference structure,based on static Fourier interferometer system was designed.And the parameters of the system according to the development of the corresponding spectral analysis software,fast data acquisition,processing and related functions output display is realized.First,based on the introduction of optical coherence basic principle of static Fourier interferometer The basic mechanism of the system is given,spatial information into frequency domain information function was derived.Static Fourier interferometer overall structure of the system was designed.We chose a suitable light source,detector and processing circuitry.Static interference prism of dimensions,materials and structural angle space is designed.Through laboratory tests verified the feasibility of the system hardware,data and 555.0nm laser spectral distribution is obtained.After the hardware configuration is completed,in order to obtain the desired spectral distribution curve,a variety of spectral analysis algorithms were compared.Interference fringes preprocessing algorithm was designed.Spectral calibration mode has been improved.Thereby improving the ability of the system of data processing.VS-based platform,the system developed is suitable for static spectral analysis software,the main display interface,and other sub-function display interface was designed.Finally,the entire system is tested separately,and with the traditional MATLAB,under LABVIEW software environment designed for spectral analysis were compared.Experimental results show that the spectral distributions of the spectral distribution of the present spectral analysis software with MATLAB and LABVEIW spectrum treatment was similar to its peak to peak position error is less than 1nm.But noise ratio of the system is better,while higher data structure compatibility.
