摘要： Systems, methods, and devices that generate and display a holographic image(s) of a 3-D real or synthetic object scene are presented. A holographic generator component (HGC) partitions a 3-D object scene into a horizontal stack of regularly spaced vertical sub-planes that are each contributed to a respective sub-line. The HGC converts the sequence of sub-lines into a collection of diffraction patterns, which are summed up and interfered with a reference beam to generate the complete hologram, which can be or can approximate a Fresnel hologram. A multi-rate filter is employed to facilitate converting sub-lines to diffraction patterns more quickly. The multi-rate filtering can be realized using convolution in the spatial domain, realized in the frequency domain using a fast Fourier transform, and/or realized in the frequency domain using a graphic processing unit.

摘要： This invention relates to methods, apparatus, and computer program code for the holographic display of images. We describe a method of displaying an image holographically. The method includes displaying a hologram on pixels of a spatial light modulator (SLM) and illuminating the SLM such that the image is displayed in pixels of a replay field (RPF) of the hologram. The method further includes subdividing the replay field into a plurality of spatially interlaced regions, and displaying holograms for each of the interlaced regions of the replay field sequentially at different times such that in an observer's eye the interlaced regions integrate to give the impression of the image and such that interference between adjacent pixels of the replay field is reduced.

摘要： A method for generating a complex amplitude in-line hologram and an image recording device using said method makes it possible to realize high-speed processing and high-speed recording from a single off-axis hologram without limiting the spatial frequency band and without creating errors from interpolation. The complex amplitude in-line hologram is generated by performing the following in order: the acquisition of data for one off-axis hologram obtained by way of off-axis holography, and for an off-axis reference light used for obtaining the hologram; the setting of a reconstruction in-line reference light; a modulation process for performing spatial heterodyne modulation on the hologram on the basis of the phases of the reference lights; and a filtering process for performing spatial frequency filtering on the hologram modulated by the modulation process. Because spatial sampling is not performed, the limits on the viewing angle are relaxed.

摘要： A method is disclosed for reconstructing a 3D scene made of object points in a holographic display, wherein the reconstruction is visible from a visibility region. Visibility and/or covering of parts of the 3D scene corresponding to the real parameters is realized, with the reconstruction, for a viewer from every place of the visibility region. Processor means generate a spatial point matrix for defining the positions of individual object points, which are assigned predetermined intensity and phase values. Within the visibility region, a complex-value wave front for each single object point is calculated. The intensity values of the object points are multiplied with the associated visibility function, to determine a common modified wave front of the object points, transformed into the plane of a light modulator to calculate modified control values for the object points.
