3-D holographic devices with 2-beam reconstruction of wavefront

摘要

The peculiarities of wavefront reconstruction under the condition of simultaneous illumination of the volume holograms by the object and reference beams, have been considered when the reconstructing object beam partially differs from the recording object beam by its phase distribution. A real time intererometry and correlation analysis of initial and final states of the object can be carried out simultaneously under the combined illumination both for volume and plate holograms. However, the case of volume holograms is characterized by bigger efficiency which is caused by the difference of diffraction at volume and plane structures.
