Abstract
Hadamard transform spectrometry is a multiplexing technique that shares some of the advantages Fourier transform spectrometry offers (e.g. the Fellgett's, or multiplex advantage and the Connes', or frequency precision advantage). Hadamard transform spectrometry, using a liquid crystal electro-optic shutter array (LC-OSA) as a stationary Hadamard encoding mask, has proven itself to be a viable technique in obtaining Raman spectra in the near-infrared (NIR). This no-moving-parts spectrometer is capable of spectral addition and subtraction and can be easily coupled with fiber optics.
