Disclosed is a method for focusing light to a target object within scattering medium comprising the following steps: (a) illuminating a plurality of incidence beams having different incidence patterns from each other, and obtaining reflection beams which are reflected from the target object for each incidence beams by a flight time which is a arrival time of the reflection beam to a camera; (b) forming a time-gated reflection matrix using the plurality of the incidence beams and the plurality of the reflection beams; (c) applying the time-gated reflection matrix to Single Value Decomposition such that a time-gated eigenchannel corresponding to a depth of the target object is calculated; (d) illuminating an eigen incidence beam having an incidence pattern, to which the time-gated eigenchannel is applied, to the target object.
