Digital holography via electrical devices (CCD camera)‎ and liquid crystal display (SLM)‎

Abstract EN

Conventional holography has been widely useful in trade measurement, combining a high resolution charge coupled device (CCD) with a phase modulating, holographic interferometer recording and display could be realized by digital holographic technique.

Digital holographic technique has a great number of important and practical applications.

In the conventional holography hologram was detected and reconstructed by the photoconductive film.

But in the digital holography the numerical version of the conventional holographic technique, hologram is digitally detected by CCD and then displayed on the computer monitor.

By reconstruction, the hologram is written into spatial light modulator (SLM), then illuminating the SLM with the reference wave, the object may be reconstructed optically.

In this research the application technique of CCD/SLM in holography is theoretically studied and the experimental have been developed.
