Abstract:
Disclosed are an optical spectroscopy system using a matched filter-based broadband signal receiver for stable data extraction, and a method for controlling the optical spectroscopy system. The optical spectroscopy system may comprise: a light transmission unit for irradiating light on a particular region of a subject by means of a plurality of light sources, wherein the light irradiated from the plurality of light sources is code-modulated by means of the Walsh codes and then irradiated; and a light receiving unit for detecting emergent light which has passed through the particular region, wherein the light source is identified by demodulating the light by means of the Walsh codes.
