Abstract
An optical system for shaping a wavefront of an electric field of an input light beam to be projected into a target volume including a first optical element, a spatial light modulator used to control light distribution in at least one transverse plane in the target volume. An intermediate optical element located on an optical axis, after the first optical element on a trajectory of the light beam for modulating the phase or the amplitude of the electric field of the input light beam is included. A second optical element for modulating the phase or the amplitude of the electric field of the input light beam is used to control the axial position of the transverse plane in the target volume. The second optical element is situated on the optical axis after the at least one intermediate optical element on the trajectory of the light beam.
