A lighting system includes a light source having a broad emission spectrum, a spatial light modulator configured to modulate one or more of phase and amplitude of light irradiated from the light source to a target object, and a detector configured to detect light intensity being reflected from the target object. Additionally, the lighting system includes circuitry configured to divide an emission spectrum of light irradiated from a light source into a plurality of wavelength ranges, measure irradiated light formed with a first wavelength range to the target object, calculate a transmission matrix based on the measurement, calculate a set of other transmission matrixes, calculate a set of patterns for generating a plurality of localized illuminations, drive the spatial light modulator by a modulation signal which forms an irradiation pattern, and scan the plurality of localized illuminations on the target object.
