时空混合调制型偏振干涉成像光谱仪干涉图获取模式研究

Research on the mode of obtaining interferograms based on the temporally and spatially mixed modulated polarization interference imaging spectrometer

基于自行研制的时空混合调制型偏振干涉成像光谱仪(TSMPIIS),提出了一种新的干涉图和光谱的获取模式,分析了干涉数据的排列方式,详细阐述了不同时刻获得的一系列干涉图组合的方法,并由TSMPIIS获得了单色光和复色光的干涉图.理想的干涉图和复原光谱充分显示了这种探测模式的优越性,如宽场、高探测灵敏度和高通量等.

Based on the temporally and spatially mixed modulated polarization interference imaging spectrometer （ TSMPIIS） developed by us,a novel mode for obtaining interferogram and spectrum is proposed. The interference data arrays acquired with this mode are analyzed,and the method for combining a series of interferograms at different moments is explained in detail. Furthermore,the interferograms of monochromatic light and polychromatic light obtained by TSMPIIS are processed. The satisfactory interferogram and reconstructed spectra show the superiority of this detection mode,such as wide field of view,high detection sensitivity and high throughput,etc.
