Abstract
Selected combinations from three or more light excitation wavelengths are serially impinged on a sample based on an encoding pattern. A plurality of spectra is detected from the sample responsive to respective ones of the selected combinations of light excitation wavelengths. A shifted Raman excitation spectral component and a non-shifted spectral component characteristic of the sample are identified based on the plurality of spectra.
