介绍了基于分体式Sagnac干涉仪的静态高通量干涉成像光谱技术的基本原理，设计并实现了长波红外宽波段“等比消偏振”分光膜系，给出了干涉仪尺寸的设计方法并利用TracePro软件验证了设计的干涉光路。使用制冷型和非制冷型探测器对该红外干涉成像光谱仪方案进行了塑料薄膜透过率测试，实验结果与高精度Michelson光谱仪测量值有较高的吻合度，证实了该方案的正确性。最后进行了推扫实验，给出了数据重排、基线校正和“切趾”等数据预处理方法，验证了该系统方案工作模式的可行性。

Based on split-type Sagnac interferometer, principles of static high-flux interferential imaging spectroscopy were introduced. Equal-ratio depolarizing beam-splitting films working in long-wave infrared were designed and achieved. Design methods of interferometer sizes were given, and interferential light path was verified through TracePro software. By utilizing cryogenic and noncryogenic detectors, the project of infrared interferometer imaging spectrometer was tested with a plastic film transmittance. Measured values from the test turned out to be highly matching with those of high precise Michelson spectrometer, which verified the accuracy of that project. In the end, methods about data rearrangement, baseline correction and apodization were given to preprocess data from push-broom experiment. The results, in turn, verified the feasibility of that systematic working mode.
