摘要： The invention relates to a display device, in particular a head-mounted display or hocular, having a spatial light modulator and a controllable light-deflecting device for generating a multiple image of the spatial light modulator, which consists of segments, the multiple image being produced at least with a predefinable number of segments which determines the size of a visible area within which a 3D-scene holographically encoded in the spatial light modulator can be reconstructed for observation by an eye of an observer.

摘要： Laser 3D imaging techniques include splitting a laser temporally-modulated waveform of bandwidth B and duration D from a laser source into a reference beam and a target beam and directing the target beam onto a target. First data is collected, which indicates amplitude and phase of light relative to the reference beam received at each of a plurality of different times during a duration D at each optical detector of an array of one or more optical detectors perpendicular to the target beam. Steps are repeated for multiple sampling conditions, and the first data for the multiple sampling conditions are synthesized to form one or more synthesized sets. A 3D Fourier transform of each synthesized set forms a digital model of the target for each synthesized set with a down-range resolution based on the bandwidth B.

摘要： A projection device is provided for finally displaying a clear desired target image while shortening time until the target image is displayed, the projection device including: a light source; a spatial modulation element reflecting light from the light source by a display unit displaying a phase distribution of a target image; a modulation element control means that performs, in parallel by different arithmetic units, first processing of generating a phase distribution of the target image and second processing of generating a phase distribution of the target image by processing with a calculation cost higher than the first processing, and displays a phase distribution generated by the second processing on a display surface of the spatial modulation element after displaying a phase distribution generated by the first processing on a display surface of the spatial modulation element; and a projection means that projects reflected light from the spatial modulation element.

摘要： The present invention relates to a light modulator device with a spatial light modulator, a structured polarizer means, a controllable polarization means and a light wave multiplexing means. The spatial light modulator comprises discretely addressable modulator cells. Two modulator cells each are combined to form a modulation element. The modulator cells modulate light waves which are capable of generating interference of a propagating light wave field with holographic information in a spatially structured way such that a specifiable spatial distribution of object light points of a three-dimensional scene is holographically reconstructed. The modulator cells of each modulation element are adjacently arranged regarding the direction of propagation of the light wave field. The light which is modulated by adjacently arranged modulator cells is given different polarization states by the structured polarizer means.

摘要： An apparatus for the recording and multiplexing of pulsed reflection holograms made possible with the invention of the Hollow Core Photonic Crystal Fiber is disclosed herein. This holographic imaging apparatus uses the Hollow Core Photonic Crystal Fiber as a waveguide in which the highly coherent property of the lightwave required for recording interference fringes can propagate through this waveguide without this coherency of the lightwave diminishing. This apparatus enables the multiplexing of several reflection holograms in a single recording medium using the reference beam with several object beams in sequenced intervals of time and space; several multiplexed recordings are made within a brief interval in time with the object beam emanating from incremental points in space; around a 120 degree tangential arc in space to achieve parallax around this 120 degree tangential arc. This disclosure makes possible apparatus which is transportable and shoulder mountable for pulsed reflection holography.

摘要： For comfortable viewing of a 3-D scene at various viewing angles, a display having a large tracking range for a variable viewer distance is required. A controllable light-influencing element deflects light in coarse steps in a viewer range. Within said steps, the light is deflected by a further controllable light-influencing element continuously or with fine gradation. The light modulation device is suitable in holographic or autostereoscopic displays for guiding the visibility ranges of the image information to be displayed so as to follow the eyes of the viewers.

摘要： A method of imaging includes illuminating a sample spaced apart from an image sensor at a multiple distances. Image frames of the sample obtained at each distance are registered to one another and lost phase information from the registered higher resolution image frames is iteratively recovered. Amplitude and/or phase images of the sample are reconstructed based at least in part on the recovered lost phase information.
