20100149314 | Method for Rendering and Generating Color Video Holograms in Real Time - A method is disclosed for rendering and generating color video holograms for a holographic reproduction device having at least one light modulation means, wherein a scene divided into object points is encoded as a whole hologram and which can be seen from as a reconstruction a visibility region, which is located within a periodicity interval of the reconstruction of the video hologram. The visibility region defines a subhologram together with each object point of the scene to be reconstructed and the whole hologram is formed from a superposition of subholograms, wherein a 3D rendering graphic pipeline structures a scene represented by image data with depth information into object points and determines and provides at least color and depth information for the object points. | 06-17-2010 |

20130050409 | DYNAMICALLY RECONFIGURABLE HOLOGRAMS FOR GENERATING COLOR HOLOGRAPHIC IMAGES - Various embodiments of the present invention are directed to negative refractive index-based holograms that can be electronically controlled and dynamically reconfigured to generate one or more color three-dimensional holographic images. In one aspect, a hologram comprises a phase-control layer having a plurality of phase modulation elements. The phase-modulation elements are configured with a negative effective refractive index and selectively transmit wavelengths associated with one of three primary color wavelength. The hologram also includes an intensity-control layer including a plurality of intensity-control elements. One or more color three-dimensional images can be produced by electronically addressing the phase-modulation elements and intensity-control elements in order to phase shift and control the intensity of light transmitted through the hologram. A method for generating a color holographic image using the hologram is also provided, as is a system for generating a color holographic image. | 02-28-2013 |

20150296203 | Dynamic Autostereoscopic Displays - Display devices can be used to provide display functionality in dynamic autostereoscopic displays. One or more display devices are coupled to one or more appropriate computing devices. These computing devices control delivery of autostereoscopic image data to the display devices. A lens array coupled to the display devices, e.g., directly or through some light delivery device, provides appropriate conditioning of the autostereoscopic image data so that users can view dynamic autostereoscopic images. Methods and systems for calibrating a hogel display are also described, including generating calibration hogel data corresponding to a calibration pattern; generating a hogel light field from the calibration hogel data; detecting the hogel light field; and determining calibration data by analyzing a set of hogel properties in response to detecting the hogel light field. The methods and systems may further include generating a calibrated hogel light field by generating calibrated hogel data using the calibration data. | 10-15-2015 |

20160187849 | Coherent Diffractive Imaging With Arbitrary Angle of Incidence - Apparatus and methods for coherent diffractive imaging with arbitrary angle of illumination incidence utilize a method of fast remapping of a detected diffraction intensity pattern from a detector pixel array (initial grid) to a uniform spatial frequency grid (final grid) chosen to allow for FFT on the remapped pattern. This is accomplished by remapping the initial grid to an intermediate grid chosen to result in a final grid that is linear in spatial frequency. The initial grid is remapped (generally by interpolation) to the intermediate grid that is calculated to correspond to the final grid. In general, the initial grid (x,y) is uniform in space, the intermediate grid ({tilde over (x)},{tilde over (y)}) is non-uniform in spatial frequency, and the final grid ({tilde over (f)} | 06-30-2016 |
