Abstract

In digital holography a CCD camera records optically generated holograms which is then reconstructed numerically by a calculation of scalar diffraction in the Fresnel approximation. The digital photography facilitates real time transmission of the message via traditional communication methods. In this paper we review the principle of digital holography and its application to the 3D image encryption-decryption, and presented our experimental results of firearm identification recording using digital holography and their numerical reconstructions.
