研究了基于Savart偏光镜的偏振干涉成像光谱仪在时空混合调制模式下图像形成、数据分布的特点,论证了视场补偿型偏振干涉成像光谱仪更适用于单色光条件下的时空混合调制工作模式,并提出了时空混合调制模式下数据采集与处理的基本原理及其需要注意的问题与解决方法.最后,应用这种方法对实验获取的干涉图进行了数据处理,并成功复原出了光谱.
A new method of the interferogram formation,recording and processing is proposed for the polarization interference imaging spectrometer. According to the regularities of the optical path difference distribution on the detector,the wide-field-of-view polarization interference imaging spectrometer (WPIIS) is proved to be much suitable for working under temporally and spatially mixed model. In addition,the originally experimental interferogram obtained by WPIIS is processed in this new way,the satisfactory result of interference data and reconstructed spectrum proved that the method is exact and useful.
