Theoretical comparison of singly-multiplexed Hadamard transform spectrometers to scanning spectrometers
Abstract
A general mathematical framework within which the relative performance of singly-multiplexed Hadamard Transform Spectrometers (HTS) and conventional scanning spectrometers may be compared is presented. The theoretical multiplex advantage (Fellgett advantage) is calculated for spectrometers operating in two spectral regions. Predictions are verified by computer simulation of various characteristic spectra. Based on these results some conclusions concerning the practical application of HTS systems are presented.
