Paper Abstract

Method for the recording and reconstruction of 3D images of objects when using a so-called reference-free selectogram is suggested. According to this method, the light scattered by the object is filtered by a horizontal slit and is then split into two components with the help of a diffraction grating that is positioned just in front of a thick-layered photographic plate. The interference pattern that originates as a result of the interaction of the components formed by the diffraction grating is recorded in a light-sensitive material in a form of a 3D deep hologram. The reconstruction of the selectogram is performed by the light scattered by a diffusing screen that is positioned in a so-called window of the system. The analysis of the processes of the selectogram recording and reconstruction in a coherent and noncoherent light is carried out and some properties of the reconstructed image are considered. It is also shown that the structure of the 3D hologram recorded by the system does not practically depend on the wavelength of the recording light. The advantages of the reference-free selectogram are low requirements as to the coherence of the recording and reconstructing light and the insensitivity to the vibrations of the setup during the recording.
