ABSTRACT:
In a polychrometer and a method for correcting stray light of the polychrometer, relative spectral (inter-pixel) distribution of stray light independent of a spectral distribution of an incident light is obtained, intensity coefficient of the stray light is calculated according to spectral (inter-pixel) distribution of the incident light, spectral (inter-pixel) distribution of the stray light included in a spectral (inter-pixel) distribution of an incident light is estimated and corrected. Thus, the stray light can be more accurately corrected as compared with a conventional case where stray light distribution is directly estimated from an incident light.
