摘要： A shared optic assembly for combined flood and dot illumination modules is disclosed. The shared optic assembly includes a first high-powered VCSEL element for providing a flood beam and a second high-powered VCSEL element for providing a dot beam, where both the first and second VCSEL elements share the same optics and are incorporated onto the same module for space savings.

摘要： An illumination device includes a laser source, a conventional diffuser element, and an extender optic with a curved interior surface and a curved exterior surface. Light emitted by the laser source with a given field of illumination (FOI) is received by the conventional diffuser element and outputted towards the interior surface of the extender optic with an increased FOI; the exterior surface of the extender optic then outputs the light received by the interior surface as light with an even greater FOI usually in the range of 120°-185°.

摘要： Transmission assemblies to project illumination from an edge of an electronic device are disclosed. In some examples, the transmission assemblies include an optical source to generate laser light. An optical focusing element to focus the laser light. And a transmitting optical element is arranged at a bezel proximate an external edge of the electronic device. The transmitting optical element receives the laser light from the transmitting optical element and to project the laser light through the bezel to illuminate an object of interest

摘要： VCSEL-based flood illuminators are fabricated to be compact and surface-mounted devices. A substrate is constructed as a panel array having top and bottom electrodes. Individual ones of the VCSEL dies are mounted in electrical communication with pairs of the top electrodes. The VCSEL dies are encased in an encasement disposed on the top surface of the substrate, and a diffuser structure is nano-imprinted adjacent each of the VCSEL dies. The encasement can use a potting resin and a polymer layer. The potting resin encases the VCSEL dies. The polymer layer is softer and is disposed on the potting resin. Nanoimprint lithography forms the diffuser structures in the polymer layer. The panel array is then singulated to form the individual VCSEL-based flood illuminators.

摘要： A display includes a stack that includes, from top to bottom: a display layer including an array of spaced pixels and/or spaced subpixels and an array of spaced transmission spaces, wherein each transmission space is defined by a spacing between a subset of the spaced pixels and/or spaced subpixels; a micro-lens array (MLA) layer including an array of micro-lenses, wherein each micro-lens includes a curved surface; and a laser light emitting (LLE) layer including an array of lasers, wherein the curved surfaces of the micro-lenses face the LLE layer.

摘要： An opto-electronic device to distribute an ultra-wide field of illumination is disclosed. In examples, the electronic device includes an optical source to generate light and a diffuser to receive and distribute the light. The diffuser includes a plurality of extensions, each having a reflective surface arranged at an angle to cause total internal reflection of an incident light ray, and an exit surface arranged at an angle relative to the reflective surface and configured to direct the light ray at one or more transmission angles different from an incident angle.
