Abstract
Methods and systems for spectroscopy are provided. Exemplary methods include: illuminating, with a tunable laser, an analyte with first light; detecting, with a filtered sensor, a first Raman signal; illuminating, with the tunable laser, the analyte using second light; detecting, with the filtered sensor, a second Raman signal, the second Raman signal being shifted from the first Raman signal by a second predetermined increment; illuminating, with the tunable laser, the analyte using third light; detecting, with the filtered sensor, a third Raman signal, the third Raman signal being shifted from the second Raman signal by the second predetermined increment; constructing a Raman spectrum using the first Raman signal, the second Raman signal, and the third Raman signal; and determining at least one molecule of the analyte using the Raman spectrum and a database of predetermined Raman spectra.
