Applied Research on Liquid Crystal Spatial Modulators in Hadamard TransformSpectrometers--Quick and Accurate Decoding Methods

摘要

This article studies liquid crystal spatial light modulator (LC-SLM) functioningas a fixed, unmoving encoding mask applied in Hadamard transform spectrometers (HTS). It puts forward a fast and accurate decoding method, and offers improvements in root mean square signal to noise ratios associated with liquid crystal spatial light modulators.
