Abstract
A method for analyzing an optical signal comprising: directing the optical signal into a scanning spectrometer system comprising a variable-wavelength filter and a detector; continuously modulating the variable-wavelength filter at a given modulation frequency to produce a time-based waveform; measuring the time-based waveform with the detector; converting the time-based waveform into a frequency spectrum comprising harmonics of the modulation frequency; and comparing the harmonics of the modulation frequency to premeasured harmonic spectra in a reference database.
