Because of the fact that the index of refraction varies as a function of the wavelength, the positions of focal planes of various wavelengths also vary with wavelength, which will affect the resolving power of the hyperspectral imager. Based on the image principle of pushbroom hyperspectral imager, the method of tilting image plane was adopted after having tested and analyzed the positions of focal planes of these monochromatic lights. It can reduce the effects of chromatic aberration of the imager’s optical system, and make the imager accord with the request of the resolving power. Then, the effects on performance were discussed.
