In-line hologram with synthesized opposite-phase internal reference
2013 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2013A technique for improving phase-less measurements for holographic imaging is presented. By interchanging the radiated reference wave with a synthesized internal signal, the hologram can be further exploited by enabling advanced control of the reference.

Optics and Spectroscopy (English Translation of Optika I Spektroskopiya), 2011
The possibility of the aberration-free reconstruction of a synthesized hologram-Fresnel projector in the case when the angles of incidence of the reconstructing plane wave exceed the angle of incidence of the plane reference wave during hologram synthesis is shown.

Methods of increasing the resolving power and depth of field of synthesized hologram-projectors
Journal of Optical Technology (A Translation of Opticheskii Zhurnal), 2016This paper discusses the problem of increasing the resolving power of synthesized Fresnel hologram-projectors and increasing the depth of field of the images reconstructed by them. This work was applied to the case of the holograms of a two-dimensional object—for example, a photolithographic photomask or the working zone of optical pincers.

Problem of twin-image elimination in 2-D computer synthesized hologram
SPIE Proceedings, 2007It is well known that one of the basic functions of security holograms is the maximal complication of their nonauthorized reproduction, in other words - counterfeiting. To solve the problem, concealed images that can be observed only under special conditions are placed into a structure of the hologram.

Particle size analysis using computer-synthesized holograms
IEEE Journal of Quantum Electronics, 1973A holographic correlation method permits the determination of the diameter and size distribution of suspended particles with diameters from 1 microm to 10 microm. The method uses synthetic holograms calculated from the Mie scattering theory.

Methods of synthesizing focused-image holograms
Journal of Optical Technology, 2013This paper discusses the main stages of the synthesis of focused-image holograms. It is established that the key problem of the synthesis when the projection objective has aberrations is to compute the complex amplitude of the object wave in the plane of the hologram. A high-throughput method of solving this problem is developed.

Synthesizing hologram–projectors for photolithography on nonplanar surfaces
Journal of Optical Technology, 2015This paper discusses how binarization and diffuse illumination of an object affect the depth of field of an image reconstructed by means of synthesized Fresnel hologram–projectors. It presents the results of an experimental study that confirm the possibility and efficiency of using a specialized software complex to synthesize and reconstruct Fresnel ...
