Abstract: On the basis of a brief description of the interference imaging principle of static large field of view polarization interference imaging spectrometer (SLPIIS), throughput of the SLPIIS is emphatically analyzed and calculated. The relation of throughput with deviation is deduced under the polarized direction of polarizer and the direction of half wave plate'slight axis deviating from ideal direction. Throughput value in the maximum modulation depth is given. The SLPIIS has wide range of wave length, simple structure, ultra-compact and large field of view compensation function, high stationary, high throughput, and is suitable for remote sensing of aviation, space-light and weak signal survey. Therefore it has broad prospects of application in military and civil.
