Holography in (2+1)-dimensional cosmological models
The cosmic holographic principle suggested by Fischler and Susskind has been examined in (2+1)-dimensional cosmological models. Analogously to the (3+1)-dimensional counterpart, the holographic principle is satisfied in all flat and open universes. For (2+1)-dimensional closed universes the holographic principle cannot be realized in general. The principle cannot be maintained, neither introduc...
متن کاملHolography, brane intersections and six-dimensional SCFTs
We study supersymmetric intersections of NS5-, D6and D8-branes in type IIA string theory. We focus on the supergravity description of this system and identify a “near horizon” limit in which we recover the recently classified supersymmetric seven-dimensional AdS solutions of massive type IIA supergravity. Using a consistent truncation to sevendimensional gauged supergravity we construct a unive...
متن کاملDigital Holography and Three Dimensional Imaging (DH)
We have investigated the image type full-color computer-generated hologram that has full parallax and can be reconstructed with three color LEDs. The object of the hologram is processed from 3D computer graphics polygon data and has shaded surface with hidden surface removal. The optical reconstructed image from the printed hologram is evaluated. © 2011 Optical Society of America OCIS codes: 09...
متن کاملHolography, Dimensional Reduction and the Bekenstein Bound
We consider dimensional reduction of the lightlike holography of the covariant entropy bound from D + 1 dimensional geometry of M × S1 to the D dimensional geometry M . With a warping factor, the local Bekenstein bound in D+ 1 dimensions leads to a more refined form of the bound from the D dimensional view point. With this new local Bekenstein bound, it is quite possible to saturate the lightli...
متن کاملFour dimensional phase unwrapping of dynamic objects in digital holography.
We present a new four-dimensional phase unwrapping approach for time-lapse quantitative phase microscopy, which allows reconstruction of optically thick objects that are optically thin in a certain temporal point and angular view. We thus use all four dimensions of the dynamic quantitative phase profile acquired, including the angular dimension and the temporal dimension, in addition to the x-y...
