Abstract
An apparatus includes a low-coherent light source configured to emit an electromagnetic wave; a spatial light modulator configured to modulate a wavefront of the electromagnetic wave; an interferometer including a movable mirror to set a depth of a medium to be irradiated by the electromagnetic wave and a beam splitter configured to the electromagnetic wave into a reference beam and an object beam; a detector to detect information about an interference pattern formed by the object beam coming from the medium via the beam splitter and the reference beam reflected by the movable mirror; and a controller configured to control the spatial light modulator, based on the information, to form a modulated wavefront for irradiating the medium.
