Studies on Hadamard Transform Fluorimetry

Hadamard transform spectroscopy has been investigated since the later 1960's and early 1970's. It was demonstrated that the application of Hadamard transform technique to spectroscopy can facilitate multichannel detection of weak signal. It can be appplied not only to component analysis, but to image analysis. Now, it has been widely used in infrared spectrometry, Raman spectrometry and photothermal deflection analysis. But its application to molecular fluorimetry has not been reported up to now.
