Abstract: An optical element, wherein axially symmetric or not, an output surface of which contains a plurality of indentations configured to increase a degree of divergence of light that is incident onto such surface through an input surface of the optical element. In one implementation, each of the indentations defines a corresponding aspheric lenslet the plurality of which encircles the central opening in the optical element. The optical element can be configured as a lightguide having the specified output surface. An illumination system for a laparoscope employing such optical element as an addition to the optical fiber bundle of the laparoscope or as a fiber bundle itself that has the specified output surface.

Abstract: A tiled head-mounted display device, comprising: an optical component including a plurality of prisms with free-form surfaces, each prism being a wedge prism comprising a first optical surface, a second optical surface and a third optical surface; and a display component including a plurality of micro-displays, wherein the number of the micro-displays and the number of the prisms with free-form surfaces is identical. The tiled head-mounted display device according to the present invention is compact and light, provides wide field of view and high resolution, especially for the optical tiling head-mounted display device, the exit pupil planes of each display channels are coincident, thus avoiding pupil aberration and keeping exit pupil diameter and eye clearance same as the single ocular. There is no resolution variance throughout the entire field of view, thus preventing extra trapezoid distortion.

Abstract: Near-to-eye systems and head-mounted displays and more particularly but not exclusively to an optimized freeform wedge-shaped prism design having free-form surfaces efficiently mathematically represented and configured to provide both high resolution and a large exit pupil heretofore unachieved.

Abstract: An extended depth-of field microscope includes (a) a microdisplay having an array of emitters capable of illuminating a sample with structured illumination, (b) an image sensor for capturing an image of the sample, and a microscope objective configured to direct the structured illumination toward the sample and direct light from the sample toward the image sensor, wherein the microscope objective has tunable focal length and is object-space telecentric such that tuning of the focal length does not substantially affect magnification of either one of the image formed on the image sensor and the structured illumination projected into object space.

Abstract: The present invention relates generally to stereoscopic displays, and more particularly, but not exclusively, to stereoscopic displays with addressable focus cues.

Abstract: Multilayer high-dynamic-range head-mounted display.

Abstract: A heat dissipation fan structure capable of showing a pattern of light includes a circuit board, a light guide plate, a light-permeable element, and a vane assembly sequentially connected together. The circuit board is provided with a light emission unit. The vane assembly has a light-permeable wall made of a light-permeable material. The light emitted by the light emission unit is evenly diffused by the light guide plate, passes through the light-permeable element, and is rendered into a specific pattern (e.g., a decorative design and/or characters) by the light-permeable portion of the light-permeable element, wherein the light-permeable portion is shaped according to user needs. The light-permeable material of the light-permeable wall of the vane assembly allows the decorative design and/or characters of light to be seen externally. The heat dissipation fan structure, therefore, can show a pattern of light in addition to dissipating heat.

Abstract: The present invention relates generally to a head-mounted projection display, and more particularly, but not exclusively to a polarized head-mounted projection display including a light engine and a compact, high-performance projection lens for use with reflective microdisplays.
