Abstract
In this work, we analyzed the influence of Bragg matching on the recording and reconstruction of animated holograms on thick media. It is shown that in order to prevent overlapping of images reconstructed from different holograms on a CCD-type receiving device (charge-coupled device), it is very important that two requirements are met, or at least one of them: when restoring an animated hologram, the reference beam usually overlaps several holograms, however, only one reconstructed image should fall on the CCD, the one that we want to read from the hologram we need; the reference beam falls on an area where several holograms are recorded, however, only one hologram we need is restored, i.e. the restoration circuit is built in such a way that the reference beam has the ability to filter out unnecessary images. This sampling capability is specified by changing the characteristics of the reconstruction wave relative to the characteristics of the recording reference wave. These include changes in the angle of incidence, phase characteristics of the wave, wavelength, etc. Restoration with other characteristics leads to a sharp decrease in the diffraction efficiency of the hologram to negligible values.
