Abstract

The mechanism of wavefront reconstruction by a geometric-optical reflection of reconstructing light from surfaces with constant phase differences between the object and reference waves used to record the interference fringe structure in the medium bulk is analyzed. This mechanism is compared with the holographic one. Experiments in volume medium and in planar optical waveguide were carried out. Several types of achromatic optical elements are proposed. The optoacoustic focusing element, which can create a great local stress in a special shaped area inside the matter, is discussed. The possibility of the ultrashort pulse temporal reconstruction is demonstrated.
