Abstract: Disclosed is a method of processing a Raman spectroscopy signal. The method includes: obtaining a first resolution of Raman spectroscopy by irradiating a target sample with broadband excitation light; calculating a Raman spectroscopy signal corresponding to the Raman spectroscopy of the first resolution; and calculating a signal corresponding to a second resolution of Raman spectroscopy that is higher than the first resolution by deconvoluting a Raman light signal.
