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. By avoiding photographic film recording and physical reconstruction by illuminating the photographic plate with a laser in traditional holography, digiral photography facilitates real time transmission of the message via traditional communication methods. In this paper we present the application of digital photography to firearm identification recording and the digital filtering technique for eliminating the zero-order diffraction and virtual image in numerical reconstruction.
