Abstract
A single-channel phase conjugation apparatus includes a spatial light modulator and a single-channel optical sensing and generating unit. The spatial light modulator receives a light having a wavefront scattered by a scattering object. The single-channel optical sensing and generating unit senses a phase control wavefront of an output light focused by the spatial light modulator and outputs a light having a phase conjugation wavefront by changing a direction of the output light in a reverse direction depending on the phase control wavefront.
