Abstract : A study is made on liquid crystal spatial light modulator (LC-SLM), used as a stationary encoding mask of Hadamard transform spectrometer (HTS), and thus a fast and accurate decoding method is proposed; the improvement is given in terms of root-mean-square of the signal-to-noise ratio produced by the LC-SLM mask. jg p.5
