%X Theory and experiments of a new spectrochemical analysis technique using a white-light image processing system are described. The spectrochemical analysis can be accomplished in three steps: (1) spatial encoding of two spectrograms to be tested, (2) color filtering at the Fourier plane in white-light optical image processor, and (3) colorimetric measurement in the output plane. Compared with existing methods of spectrochemical analysis, the present technique requires only one white-light processor and a single film of encoded film, therefore it is much simpler and more economical to use in practical applications.
