Abstract
An apparatus for detecting at least one species using Raman light detection includes at least one laser source for illuminating a sample containing the at least one species. The apparatus also includes a modulating element for modulating a spatial relationship between the sample and the light beams to cause relative positions of the sample and the light beams to be oscillated, in which Raman light at differing intensity levels are configured to be emitted from the at least one species based upon the different wavelengths of the light beams illuminating the sample. The apparatus also includes a Raman light detector and a post-signal processing unit configured to detect the at least one species.
