چکیده

The light field is a 4D recording that includes the positional and directional information for incoming rays of an image. A hologram is a recording that reconstructs the complex wavefront of an image to include parallex and depth cues. We relate these two concepts using the Wigner distribution, and attempt to recreate a light field recorded scene using a phase only hologram.

Computational hologram synthesis and representation on spatial light modulators for real-time 3D holographic imaging

In dynamic computer-generated holography that utilizes spatial light modulators, both hologram synthesis and hologram representation are essential in terms of fast computation and high reconstruction quality. For hologram synthesis, i.e. the computation step, Fresnel transform based or point-source based raytracing methods can be applied. In the encoding step, the complex wave-field has to be o...

In this paper a method for digitally recording four quarter-reference-wave-holograms (by CCD) in a Mach-Zehnder interferometer setup, and reconstructing the object wave-front by numerical method is presented. The terms of direct transmission, auto-correlation and conjugate wave in the four wave reconstruction are cancelled out and only one original object wave is left after overlapping. Reconst...

Multiplexed phase–conjugate holographic storage using an intermediate buffer hologram

Volume holographic storage combines fast, parallel readout (because each hologram stores a large data page) with high density (because many holograms are multiplexed within the same volume). Phase-conjugate readout has been proposed as a way to eliminate the precision optics that recent demonstrations have relied upon to image the pixels of the input spatial light modulator (SLM) onto those of ...

Real-time phase-only color holographic video display system using LED illumination.

A real-time full-color phase-only holographic display system generates holograms of 3D objects. The system includes a 3D object formed by voxels, an internet-based transmission capability that transmits the object information to the server, a real-time hologram generation unit, and a holographic display unit with incoherent illumination. The server calculates three phase holograms for RGB compo...

Diffraction properties of substrate guided- wave holograms

Substrate guided-wave (SGW) holograms are recorded by guiding the reference wave to the hologram using an optical substrate.1'2 As compared to conventional holographic recording systems, SGW systems are compact, portable, robust, and easy to align. Since the illuminating beam is encapsulated within the substrate and only the holographic image is diffracted, the hologram can be viewed close to t...
