System and method for analyzing of light source

PURPOSE: A system and method for analyzing of light source is provided to minimize the structure which unit cells are arranged by mounting an optical signal monitoring device. CONSTITUTION: A light source monitoring device(720) monitors the light and includes a unit cell array lined up according to a pre-set arrangement standard by unit cells obtaining photo current by selecting only the light corresponding to different wavelength standard from the light selects. A light source characteristic analysis device(710) receives the wavelength and photo current of the light from the light source monitoring device. The light source characteristic analysis equipment produces an optical characteristic value of the light based on the wavelength and photo current of the received light.
