An infinity mirror includes a light-transmissible and reflective layer, a reflective layer, a light-transmissible layer and at least one light-emitting element. The light-transmissible and reflective layer is disposed on a top surface of the light-transmissible layer. The reflective layer is disposed on a bottom surface of the light-transmissible layer. The at least one light-emitting element emits a light beam. The light-transmissible layer includes a pattern zone and a non-pattern zone. There is a height difference between the pattern zone and the non-pattern zone of the light-transmissible layer. The infinity mirror can provide a multi-mirror image effect.

A view redirecting system for use on a mobility device to redirect a user's view to a more favorable orientation is disclosed. One embodiment includes a first structure having a convex first reflective surface, a second structure having a flat second reflective surface and a third structure. The third structure being an adjustable structure and configured for connecting said first and second structures together. The first structure and the second structure are configured to be positioned such that the first reflective surface and the second reflective surface are facing each other at angle up to and including ninety degrees. The third structure configured to maintain the angle. The system is arranged to redirect a user's view from a first line-of-sight to a second line-of-sight by light interacting with the reflective surfaces. The system being configured for attachment to a structural member of the mobility device.

Embodiments herein describe AR systems that provide occluded AR content to a user while maintaining the perspective of the user. In one embodiment, the AR system includes an optical cloak that contains a mask display device and an AR display device and one or more focusing elements for focusing light captured from the user's environment. As the light enters the optical cloak, the mask display device occludes a portion of the user's view to generate a black silhouette. The AR system then combines AR content displayed by the AR display device with the image of the environment such that the location of the AR content overlaps with the location of the black silhouette. Furthermore, the spacing and characteristics of the focusing elements is set to maintain the perspective of the user as the light passes through the optical cloak.

The invention provides an apparatus and method for illuminating, imaging and treating the retina of an eye. The apparatus (10) comprises an illuminating device (16) including a planar light source capable of producing light in a plane, such that the illuminating device (16) is capable of illuminating a circumferential line on the retina (12) and a support structure, wherein the illuminating device (16) is pivotably mountable to the support structure and is rotatable about an axis (18) which lies substantially on the plane defined by the light source, such that, in use, the illuminating device (16) may be rotated about the axis (18) to illuminate an area of the retina (12).

An optically variable areal pattern has a reflection layer and a micromirror arrangement comprising a plurality of semitransparent micromirrors developed on the reflection layer. The micromirrors are inclined with respect to the reflection layer, such that, by specular reflection, light incident on the micromirror arrangement is reflected on the semitransparent micromirrors. The incident light is reflected partly in a first direction and partly in a second direction that is different from the first direction, in that it passes through the semitransparent micromirrors, impinges on the reflection layer, and is reflected there and, thereafter, again passes through the semitransparent micromirrors.

According to one embodiment, a display device includes a display, an optical unit, and a reflector. The display includes a first display region emitting a first bundle of rays and a second display region emitting a second bundle of rays. The optical unit includes first and second emission regions transmitting the first and the second bundle of rays. The reflector includes a first reflection region reflecting the first bundle of rays, and a second reflection region reflecting the second bundle of rays. The optical unit forms a first focal point of the first bundle of rays between the optical unit and the reflector, and forms a second focal point of the second bundle of rays between the optical unit and the reflector. A distance between the first emission region and the first reflection region is shorter than a distance between the second emission region and the second reflection region.

An optical element is configured by connecting a plurality of tiles each constituted by a plurality of reflective optical elements, and is formed in a shape having a plane surface. The tiles configuring the optical element are formed such that outer shapes on the plane surface of the tiles have at least two different triangular shapes, while an end surface of each tile is provided with a light shielding part.
