Compressive Sensing Hyperspectral Imaging by Spectral Multiplexing with Liquid Crystal

Hyperspectral (HS) imaging involves the sensing of a scene’s spectral properties, which are often redundant in nature.The redundancy of the information motivates our quest to implement Compressive Sensing (CS) theory for HS imaging.This article provides a review of the Compressive Sensing Miniature Ultra-Spectral Imaging (CS-MUSI) camera, its evolution, and its different applications.The Antenna Adaptor CS-MUSI camera was designed within the CS framework and uses a liquid crystal (LC) phase retarder in order to modulate the spectral domain.

The outstanding advantage of the CS-MUSI camera is that the entire HS image is captured from an order of magnitude fewer measurements of the sensor array, Spray Arm Retaining Bush compared to conventional HS imaging methods.
