Compressive Sensing Hyperspectral Imaging by Spectral Multiplexing with Liquid Crystal

Blog Article

Hyperspectral (HS) imaging involves the sensing of a scene’s spectral properties, which are Disk 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 CS-MUSI camera was designed within the CS framework and uses a liquid crystal (LC) phase Bath 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, compared to conventional HS imaging methods.
