Abstract
A fluorescence subtracted Raman spectroscopy apparatus uses a wavelength modulated tunable filter as the spectrometer. The wavelength modulation results in an amplitude modulation on the detected optical signal. By using a frequency selective detection technique, the Raman signal is amplified and extracted from the fluorescence background.
