Abstract
According to the needs of creating holograms of 3D computer models, an original device for synthetizing non focused holograms has been designed and manufactured. The device composes holographic masters by projecting series of 2D views of a subject. These views are displayed by a SLM and projected through a special designed objective. The hologram is then subsequently recorded near the plane of the output pupil of the writing objective. The 3D holographic stereogram is then made by the H1-H2 copying. The main goal of the device is to create rainbow single parallax hologram masters. However, the device is able to write the holo-pixels in x-y directions, which allows us to use both parallaxes. This is used for the research in the field of RGB rainbow masters, reflection hologram masters and implementation of kinetics to the final stereogram. In this paper, the method and the design of the recording device is presented.
