摘要: A light-emitting layer of an apparatus includes an addressable array of light-emitting elements including a first light-emitting element and a periodic optical layer overlaying the light-emitting layer. The periodic optical layer includes at least a first periodic optical feature having a first optical power and a second periodic optical feature having a different optical power. A first controllable light-steering layer is disposed between the light-emitting layer and the periodic optical layer. The first controllable light-steering layer is switchable between directing light from the first light-emitting element through the first periodic optical feature and directing light from the first light-emitting element through the second periodic optical feature.

摘要: A photophoretic display device includes at least one trap light source configured to generate a trap beam, at least one illumination light source configured to generate an illumination beam, a void, and a first reflective surface. The trap beam enters the void and traps a first one or more scattering particles, the trap beam is incident on the first reflective surface at a first incidence angle and is reflected as a first reflected trap beam, the first reflected trap beam traps a second one or more scattering particles, and the illumination beam illuminates the first one or more scattering particles and the second one or more scattering particles that are trapped to generate a volumetric image.

摘要: Systems and methods are described for providing a three-dimensional display. In an example, a display device includes a light engine, a spatial light modulator, one or more directable minors, and a projection lens. Light from the light engine is modulated by the spatial light modulator, reflected by the directable mirror(s) toward the projection lens, and projected by the projection lens (e.g. onto a screen). The directable mirror(s) may include a rotatable mirror or a digital micromirror device. The spatial light modulator may be a digital micromirror device. The spatial light modulator and the directable mirror(s) are synchronized so as to generate different modulated light patterns for different positions of the directable mirror(s). The projection of different modulated light patterns in different directions may generate different views that are visible from different user perspectives.

摘要: Multiview displays include a backlight and a screen used to form a plurality of multiview pixels. Each multiview pixel includes a plurality of sets of light valves. The backlight includes a light source optically coupled to a plate light guide configured with a plurality of multibeam diffraction gratings. Each multibeam diffraction grating corresponds to a set of light valves and is spatially offset with respect to a center of the set of light valves toward a center of the multiview pixel. The plurality of multibeam diffraction gratings is also configured to diffractively couple out light beams from the plate light guide with different diffraction angles and angular offsets such that at least a portion of the coupled-out light beams interleave and propagate in different view directions of the multiview display.

摘要: Methods for determining surgical margins using an imaging device are described that use multiple cameras to image a biological sample on a turntable bathed in white light or fluorescing due to a systemically administered dye. Fluorescence farther away from an excitation light source can be compensated upon determining a 3-D position of portions of the sample. The turntable is turned and tilted in order to take enough images to prepare an animation of the sample. In a graphical user interface, the animation can be stopped, zoomed, and tilted per a user's gesture, touch, tablet-tilting, or other commands. The image manipulation can be with touch gestures entered using a sterilizable or disposable touch pen.

摘要: The invention relates to an optical system for generating a two- or three-dimensional image, the system comprising: a projection apparatus for optically transmitting image information to at least one user; an eye detection apparatus; and an imaging apparatus for imaging the image information of the projection device, so that the user can perceive said image information. The imaging apparatus comprises at least one optical hologram set, at least one of which sets is designed to be angle-amplifying. Using the projection apparatus, at least one virtual optical point is generated, or a plurality of optical points are generated such that they form at least one optical wave front, each virtual optical point being generated by the superposition of at least two coherent light waves in the region of the at least one angle-amplifying optical hologram set, and the at least one optical hologram set is used to image the at least one virtual point or the at least one optical wavefront onto the eyes of the at least one user. The respective movements of the eyes of the at least one user can be detected by the eye detection apparatus and the latter cooperates with the projection apparatus in such a way that the amount of image information is adapted according to the respective alignment of the eye and/or position of the eye in different perception regions of each eye.
