We have created a programming tool which uses image data provided by webcam connected to personal computer and gives user an ability to see the future digital hologram preview on his computer screen, before sending video data to holographic printing companies.

High Resolution Non-Line-of-Sight Imaging with Superheterodyne Remote Digital Holography
Imaging and Applied Optics 2019 (COSI, IS, MATH, pcAOP), 2019We present a novel technique for Non-Line-of-Sight imaging that borrows ideas from Multi-Wavelength Interferometry and Remote Digital Holography. Our method reaches a resolution of a few mm, which by far surpasses the resolution of conventional methods.

Characterization of Long Multi-Mode Fiber Links using Digital Holography
Optical Fiber Communications Conference and Exhibition, 2019We propose to use digital holography to characterize long multi-mode fiber links. A four segment 26.5km fiber span supporting 45 spatial modes is analyzed, showing the evolution of both mode-dependent loss and cross talk.

Phase shifting digital holography with the Hanbury Brown–Twiss approach
, 2019We report a phase shifting holography for coherence waves in the Hanbury Brown and Twiss approach. This technique relies on the wave nature and interference of the coherence waves in the two-point intensity correlation.

Abstract: Terahertz (THz) technology is combined with digital holography for THz imaging. The characteristics of the propagation behaviour of the THz pulse in free space are investigated by using numerical simulations. The algorithm is based on the angular spectrum theory.

Digital Holography Configurations
2011Some of the general characteristics of digital holographic images are illustrated using simulated examples. Holographic image location and magnification are dependent on, and therefore can be controlled by, the choice of wavelengths and reference directions and curvatures.
