Hyperspectral Imaging Camera using Wavefront??? ?????
This document describes a new approach for hyperspectral imaging using wavefront division interference. The approach uses a spatial light modulator placed in the exit pupil of an imaging system to divide the wavefront from each object point into two parts with a variable phase delay. As the phase delay is changed, an interferogram is obtained for each wavelength, allowing the spectrum at each point to be determined. The approach converts a general imaging system into a hyperspectral imaging system with only a minor impact on optical performance. A prototype optical system was built to demonstrate this new wavefront division interference approach to hyperspectral imaging.
