Abstract

A hyperspectral imaging system composed of a fore-optic and an imaging spectroscope is designed and presented. The fore-optic is a three-mirror anastigmatic telescope with a 360mm focal length to match the FPA with 1024×1024 pixels. The imaging spectroscope is based on a modified Offner 1× relay with a holographic convex grating in the place of the secondary mirror. The hyperspectral imaging system is designed for the visible-near infrared (VNIR) band with 5nm spectral and 18m ground spatial resolution from the altitude of 500km. Its many attractive features such as fast speed (F/2.5), large flat field, wide spectral range, low distortion, and compactness made it ideally suited for spaceborne remote sensing.
