Abstract
A method for irradiating a scattering medium, including irradiating a scattering medium with radiation from a laser, to form scattered radiation having a scattered field; measuring a difference in the scattered field caused by motion of a moving target in or behind the scattering medium; forming a phase conjugate of the difference to form a phase conjugate field; and irradiating the scattering medium with the phase conjugate field formed using one or more radiation modulating elements. Thus we present that movement of objects can be used as a novel guide star in Digital Optical Phase Conjugation (DOPC). By time reversal of difference of scattering fields of a moving target, light can be focused through scattering media.
