Holographic Stereograms : Three Dimensional Artwork from Computer Graphics
The goal of this thesis is to explore methods for the creation of computer generated holographic stereograms, concentrating on their potential as artwork. There is a need for strong images in this relatively unexplored medium, in which computer graphics and holography complement each other. The primary emphasis is on strong design incorporating graphical elements that enhance the three dimensio...
متن کاملReal-time shader rendering of holographic stereograms
Horizontal-parallax-only holographic stereograms of nearly SDTV resolution (336 pixels by 440 lines by 96 views) of textured and normal-mapped models (500 polygons) are rendered at interactive rates (10 frames/second) on a single dual-head commodity graphics processor for use on MIT’s third-generation electro-holographic display. The holographic fringe pattern is computed by a diffraction speci...
متن کاملInteractive Holographic Stereograms with Accommodation Cues
Image-based holographic stereogram rendering methods for holographic video have the attractive properties of moderate computational cost and correct handling of occlusions and translucent objects. These methods are also subject to the criticism that (like other stereograms) they do not present accommodation cues consistent with vergence cues and thus do not make use of one of the significant po...
متن کاملPhotolithographic fabrication method of computer-generated holographic interferograms.
We consider the fabrication of high-quality interferogram-type diffractive optical elements with conventional photolithographic techniques and compare the results with those achievable with electron-beam lithography. The fringes associated with the phase transfer function of the binary phase holographic interferogram are approximated with rectangles, which can be realized at submicron accuracy ...
متن کاملSpeckle-field digital holographic microscopy.
The use of coherent light in conventional holographic phase microscopy (HPM) poses three major drawbacks: poor spatial resolution, weak depth sectioning, and fixed pattern noise due to unwanted diffraction. Here, we report a technique which can overcome these drawbacks, but maintains the advantage of phase microscopy - high contrast live cell imaging and 3D imaging. A speckle beam of a complex ...
