Spectroscopic method and apparatus for identification of a substance using a tunable light source

Patent image
NRL

A spectroscopic detector includes a tunable light source, such as a continuously tunable, optical parametric oscillator laser; means for measuring the emitted radiation at a plurality of emission wavelengths to obtain a plurality of spectral measurement data; and a processor for processing the spectral measurement data, where the processor includes a multispectral data processing algorithm or is configured for 1) combining the plurality of spectral measurement data into a composite spectrum, and 2) applying the algorithm to the composite spectrum. The spectra such as resonant and near-resonant Raman Spectra that are acquired are more complete and contain more information. A powerful multispectral analysis code such as IHPS, CHOMPS, or ENN analyzes the acquired data points, examining details of the spectra that could not be handled by traditional methods.
