Systems and methods are directed to automatically generating a three-dimensional (3D) holographic presentation from a two-dimensional (2D) slide presentation. A network system receives an indication to generate the 3D holographic presentation, which causes automatic generation of the 3D holographic presentation by the network system. In response to receiving the indication, the network system accesses the 2D slide presentation from a user device associated with a presenter and accesses, from a mapping database, a plurality of mappings that indicate how to convert elements of each slide of the 2D slide presentation into a 3D format. The network system then transforms elements of each slide from a 2D format into the 3D format based on the plurality of mappings. The 3D holographic presentation is generated from the transformed elements by blending the transformed elements with a background and/or real-world image data captured by an image capture device.

A method and display apparatus for reducing holographic speckle when displaying holographic images are described. A target image (10) is decomposed into input images (11). A first input image includes higher spatial frequency components of the target image and is imaged using a first display method (12) to generate a first holographic display image. The second input image includes lower spatial frequency components of the target image and is imaged using a second display method (12) to generate a second display image. The first and second display images are combined for display to a user. The second display method (12) is adapted to reduce holographic speckle or include no holographic speckle compared to the first holographic display method (12) thereby reducing holographic speckle in the combined display image (13).

Digital holographic microscopy and related image processing techniques are described. A hologram captured in an image frame is split into different depths while a new hologram is being captured. Image slices of the hologram are determined and using free space impulse responses that are pre-calculated at a different precision than processing operations using the holographic data. Each computation is calculated in parallel based on the number of available processing cores and threads. The image slices are combined into a 2D array or 3D array to permit further processing of the combined array to count and size particles in the image frame. The reconstructed hologram is displayed at a subsequent image frame than that used to capture the hologram.

A light field (LF) display system for augmentation of a vehicle. The LF display system includes LF display modules that form a surface (e.g., interior and/or exterior) of a vehicle. The LF display modules each have a display area and are tiled together to form a seamless display surface that has an effective display area that is larger than the display area. The LF display modules present holographic content from the effective display area.

A floating hologram apparatus includes a display including a first output area to output a first hologram image and a second output area to output a second hologram image and a prism array positioned in front of the display and configured to refract rays of the first hologram image and the second hologram image. The prism array includes multiple prisms of which a first facet to which a ray of the second hologram image is incident and a second facet to which a ray of the first hologram image is incident have different angles.

A holographic 3D display system is described that (1) always presents true-colored and true-orthoscopic 3D images regardless of whether the object is thin or thick, or the image is virtual or real and (2) accomplishes an effective data/signal compression apparatus that accommodates to both off-the-shelf detector and display arrays, of both amicable gross array dimensions and palpable individual pixel sizes. It provides a rectilinear-transforming digital holography (RTDH) system for recording and displaying virtual, real, or both virtual and real, orthoscopic three-dimensional images, the system comprising: (a) a focal-plane compression-domain digital holographic recording/data capturing (FPCD-DHR) sub-system; (b) a 3D distribution network for receiving, storage, processing and transmitting the digital-holographic complex wavefront data signals generated by the digital complex wavefront decoder (DCWD) to at least one location; and (c) a focal-plane compression-domain digital holographic display (FPCD-DHD) sub-system located at the at least one location.

A volumetric display system including a volumetric display for displaying a scene viewable as a three-dimensional floating-in-the-air scene in a display space, enabling a user to reach a first object into the display space, a location determination unit locating real objects in the display space, providing a location of the first object when the first object is inserted into the display space, and a computer for receiving the location of the first object, detecting when the location of the first object is at a location where an object is displayed in the three-dimensional scene, thereby determining that the first object is viewable as touching the displayed object following a detection of the first object viewable as touching the displayed object, producing a new three-dimensional scene displaying the displayed object as if manipulated by the first object. Related apparatus and methods are also described.

Disclosed are methods and systems for displaying images, and for implementing volumetric user interfaces. One exemplary embodiment provides a system comprising: a light source; an image producing unit, which produces an image upon interaction with light approaching the image producing unit from the light source; an eyepiece; and a mirror, directing light from the image to a surface of the eyepiece, wherein the surface has a shape of a solid of revolution formed by revolving a planar curve at least 180 around an axis of revolution.

A system for displaying, to viewers who do not need to wear special eyewear, static three dimensional (3D) images that are dynamically augmented with two dimensional (2D) images. The system includes a holographic print with a front surface and a back opaque layer. The system includes a projector projecting light onto the front surface. The projected light includes first light reconstructing a hologram from the front surface of the holographic print and second light displaying 2D content on the front surface. The projector is positioned to cause the first light to strike the front surface within a range of hologram reconstruction angles. The projector is a video projector, and the first light is even illumination in the form of white light while the second light includes the displayed 2D content. The displayed 2D content includes animation or video content.
