Paper Abstract

The present research deals with the digital synthesis of the multiview diffractive image elements, or simply the Multiview Diffractive Images (MDIs), also known as stereographic diffractive images or holographic stereograms. These images are designed to be included in Diffractive Optically Variable Image Devices (DOVIDs) in order to make them more spectacular and visually impressive and to improve their security properties. In the present paper there are considered the computation of parameters for Diffractive Gratings (DGs) composing the MDI topology. The innovative DGs based on the curvilinear strokes are offered. They provide larger diffraction efficiency and better integrity of the scene for any variant of the Lighting and Observation (LO) as well as for the arbitrary parameters of LO geometry. There are described the original approach for computation and estimation of the polychromatic DGs intended to reproduce the complex spectral distribution of the diffracted light. There are proposed the powerful and flexible techniques for Diffractive Images (DIs) encoding and for uniting different DIs within multichannel one. The distinctions in the modes of the MDI observation, which were escaping anyone's attention until now, are discussed. The physical aspects of visual perception for diffractive images are also concerned. So, the present investigations elucidate the main topics pertinent to the diffractive images synthesis and approach to master the creation of striking ones, particularly the multiview images.
