    摘要: Embodiments of optical collimators are disclosed. For example, one disclosed embodiment comprises an optical waveguide having a first end, a second end opposing the first end, a viewing surface extending at least partially between the first end and the second end, and a back surface opposing the viewing surface. The viewing surface comprises a first critical angle of internal reflection, and the back surface is configured to be reflective at the first critical angle of internal reflection. Further, a collimating end reflector comprising a faceted lens structure having a plurality of facets is disposed at the second end of the optical waveguide.

    摘要: Optical touch detection is provided by an interactive display device including an elastomer layer, a reflector configured to transmit light having a first characteristic and to reflect light having a second characteristic, and a display positioned to output modulated light having the first characteristic through the elastomer layer and the reflector as a display image. The interactive display device further comprises a test light source positioned to output light having the second characteristic through the elastomer layer for reflection off of the reflector, and a sensor configured to receive light having the second characteristic reflected from the reflector.

    摘要: Various embodiments are disclosed that relate to scanning the direction of light emitted from optical collimators. For example, one disclosed embodiment provides a system for scanning collimated light, the system comprising an optical wedge, a light injection system, and a controller. The optical wedge comprises a thin end, a thick end opposite the thin end, a viewing surface extending at least partially between the thick end and the thin end, and a back surface opposite the viewing surface. The thick end of the optical wedge further comprises an end reflector comprising a faceted lens structure. The light injection system is configured to inject light into the thin end of the optical wedge, and the controller is configured to control the location along the thin end of the optical wedge at which the light injection system injects light.
