Abstract:
Disclosed are a time division spread spectrum code-based optical spectroscopy system capable of controlling irradiation power and a method for controlling the optical spectroscopy system. The optical spectroscopy system may comprise: a light transmission unit for irradiating light to a particular region of a subject by means of a light source, wherein the light is irradiated so that the overall energy is consistently maintained by reducing the light irradiation time and increasing the strength of the light; and a light receiving unit for collecting emergent light which has passed through the particular region.
