Abstract
An introduction to Hadamard transform spectrometry in general and Hadamard transform Raman spectrometry in particular is presented. Two generations of Hadamard encoding masks are described. Experimental details are provided for the operation of a Hadamard transform Raman spectrometer utilizing the Hadamard encoding masks described. Near-infrared Hadamard transform Raman spectra are presented to illustrate spectral subtraction, the multiplex advantage and a selective multiplex technique. With the second generation of Hadamard encoding masks available, the Hadamard transform Raman technique is now ready to begin its testing in the analytical world.
