Abstract: An image output device of the disclosure facilitates enlargement of a stereoscopic image and includes a spatial light modulator, an image irradiation unit, and an address light irradiation unit. The spatial light modulator includes a main surface, a back surface, and pixels, reflects light emitted to the main surface, and modulates a phase of the light for each pixel. The image irradiation unit irradiates the main surface with light including an optical image. The address light irradiation unit irradiates the back surface with address light including a diffraction grating pattern. Each pixel of the spatial light modulator changes a phase modulation amount according to the intensity of the address light from a back surface. The address light irradiation unit dynamically change a diffraction grating pattern's direction on the back surface. The image irradiation unit irradiates the main surface with the optical image corresponding to the diffraction grating pattern's direction.

Abstract: A vehicle for projecting holograms is described. The vehicle may include a plurality of Integrated Holographic Camera Modules (IHCMs) configured to project movable holograms. The vehicle may further include a vehicle processor communicatively coupled to the plurality of IHCMs. The vehicle processor may obtain a recording of a movable hologram from a first IHCM and determine a hologram movement from the recording. The vehicle processor may further switch a projection of the movable hologram from the first IHCM to a second IHCM when a predefined criterion is met. The vehicle processor may determine that the predefined criterion is met when the projection moves from a first IHCM projection range to a second IHCM projection range.

Abstract: A light field (LF) display system presents holographic content to one or more viewers in a public setting for digital signage applications. In some embodiments, the LF display system includes a sensory feedback assembly, a tracking system and/or a viewer profiling module. The sensory feedback assembly may comprise sensory feedback devices that provide sensory feedback to viewers of the LF display system in tandem with the presented holographic content. The tracking system may comprise cameras used to track the viewers of the LF display system. Based on a viewer's tracked position and/or tracked gaze, the LF display system may generate holographic content that is perceivable by certain viewers but not viewable by others. The viewer profiling module may identify each viewer for providing personalized holographic content and may further monitor and record behavior of viewers for informing subsequent presentations of holographic content by the LF display system.

Abstract: An example system includes a master oscillator that provides a master oscillator beam, a first fiber beam splitter that splits the master oscillator beam into a first branch and a second branch, a second fiber beam splitter that splits the first branch into an imaging branch and an amplified characteristic branch, and a compensation branch mixer that mixes the second branch and the amplified characteristic branch into a compensation branch. The example system includes transmission optics that direct the imaging branch to a target location, an imaging mixer that mixes the compensation branch and a reflected image from the target location into an imaging signal, and an acquisition device that receives the imaging signal as a final image. An example system optionally includes a mode matching lens that applies a selected wavefront characteristic to the compensation branch.
