Abstract
An apparatus for detecting at least one molecule using Raman light detection includes a substrate for supporting a sample containing the at least one molecule, a laser source for emitting a laser beam to cause Raman light emission from the at least one molecule, a modulating element for modulating a spatial relationship between the laser beam and the substrate at an identified frequency to cause the Raman light to be emitted from the at least one molecule at the identified frequency, at least one detector for detecting the Raman light emitted from the at least one molecule, and a post-signal processing unit configured to process the detected Raman light emission at the identified frequency to detect the at least one molecule.
