• CCD image sensor
• noises
• signal-to-noise ratio

The principle of home-designed novel polarization interference imaging spectrometer is discussed. The noise of novel polarization interference imaging spectrometer is analyzed, and the expression of total noise related to system throughput is deduced. The noise induced by imaging spectrometer system and CCD image sensor is extracted from spectrometer image. The signal-to-noise ratio of novel polarization interference imaging spectrometer based on such noise analyses is discussed, which proves that though luminous throughput of imaging spectrometer system has a crucial effect on the total noise, it does not affect the trend of variation in signal-to-noise ratio. A new practical guidance is thereby provided for the accurate calculation of the signal-to-noise ratio of imaging interference and the application of denoising method effectively.
