Combined Fourier hologram as a noise-resist method of synthesis 2D computer-generated hologram with single diffractive order

Braginets, E.V.; Girnyk, V.I.; Kostyukevich, S.A.; Kurashov, V.N.; Bushma, A.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2008)

In this paper, a comparative analysis of two approaches to synthesis 2D hologram, which restores optical field without conjugated images, is performed. These holograms are used in embossed rainbow protective holograms ...
Finding of the optimal parameters of animated and stereographic rainbow diffractive images

Borisov, I.S.; Girnyk, V.I.; Kostyukevych, S.A.; Grygoruk, V.I.; Kostyukevych, K.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2008)

We have considered the basic aspects of the technology of animated and stereographic rainbow images. These images can be included in Optical Security Devices (OSDs) in order to increase their structure complexity and to ...
Investigation of synthesis peculiarities inherent to computer-generated rainbow holograms of 3D images

Girnyk, V.I.; Kostyukevich, S.A.; Shepeliavyi, P.E.; Kononov, A.V.; Borisov, I.S. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2002)

This work deals with Computer-Generated Rainbow Holograms (CGRHs), which can restore the 3D images under white light. They are devoted to include in Diffractive Optically Variable Image Devices (DOVIDs) that are currently ...
Kinoform syntesis as an improved method to form a concealed image in optical security devices

Braginets, E.V.; Girnyk, V.I.; Kostyukevych, S.A.; Kurashov, V.N.; Soroka, A.A.; Moskalenko, N. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2006)

It is well known that one of the basic functions of security holograms is the maximal complication of their non-authorized reproduction, in other words – counterfeiting. To solve the problem, concealed images that can be ...
Multilevel computer-generated holograms for reconstructing 3-D images in combined optical-digital security devices

Girnyk, V.I.; Kostyukevych, S.O.; Shepeliavyi, P.Ye.; Kononov, A.V.; Borisov, I.S. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2002)

Computer-generated holograms (CGHs) integrated within combined optical-digital security devices (CO/DSDs) are described in this work. They can restore the monochrome and color 3D images in white light. To record them, the ...
Using non-organic resist based on As-S-Se chalcogenide glasses for combined optical/digital security devices

Kostyukevych, S.A.; Moskalenko, N.L.; Shepeliavyi, P.E.; Girnyk, V.I.; Tverdokhleb, I.V.; Ivanovsky, A.A. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2001)

Modern holographic protective elements used as emblems against counterfeiting are being more complicated as they should oppress criminal world. 2D, 3D, 3D rainbow holograms or simple diffraction structures protecting ...
