A self-contained interactive video display system. A projector projects a visual image onto a screen for displaying the visual image, wherein the projector projects the visual image onto a back side of the screen for presentation to a user on a front side of the screen. An illuminator illuminates an object near the front side of the screen. A camera detects interaction of an illuminated object with the visual image, wherein the screen is at least partially transparent to light detectable to the camera, allowing the camera to detect the illuminated object through the screen. A computer system directs the projector to change the visual image in response to the interaction.

Computer vision based touch screen

An interactive video window display system. A projector projects a visual image. A screen displays the visual image, wherein the projector projects the visual image onto a back side of the screen for presentation to a user on a front side of the screen, and wherein the screen is adjacent to a window. An illuminator illuminates an object on a front side of the window. A camera detects interaction of an illuminated object with the visual image, wherein the screen is at least partially transparent to light detectable by the camera, allowing the camera to detect the illuminated object through the screen. A computer system directs the projector to change the visual image in response to the interaction. The projector, the camera, the illuminator, and the computer system are located on the same side of the window.

Processing an image utilizing a spatially varying pattern

The present invention relates to a multiple access space laser communications optical system. According to the present invention, multiple optical signals containing a number of channels are simultaneously received and demultiplexed at a multiple access communication device. Separate communication signals may be multiplexed by the multiple access communication device, and transmitted through the same or a different telescope optical assembly used to receive communication signals. Double-pass reflection is used to selectively polarize signals and to ensure that signals are substantial normal to optical bandpass filters, to avoid large shifts in the wavelengths transmitted by the optical bandpass filters. The system is capable of providing discrete communications with a number of communication endpoints, regardless of where the communication endpoints are located within the field of view of the telescope optical assembly.

Multiple access space communications optical system using a common telescope aperture

The present invention provides an enhanced viewing eyepiece for a micro-display. In one embodiment, the invention is an optical imaging system that includes a prism having a first face directed toward a display to receive light from the display and direct it through a second face, a converging optical element between the second face of the prism and the display, and a reflective converging optical element adjacent the second face of the prism to receive the display light through the second face of the prism and reflect it back into the second face of the prism, the invention further includes a diverging optical element aligned with the reflective converging optical element to receive the display light reflected back into the first prism and direct it to an exit pupil.

Compact wide field of view imaging system

An enhanced illumination system for a micro-display comprises an illuminator for a reflective display panel having a light source and a prism. The prism has a first substantially planar face proximate to the light source and to the display panel, so that light propagates from the light source into the prism through the first face and is redirected to the display panel through the first face. A second face of the prism is positioned opposite the light source so that light reflected from the display panel impinges on the second face and propagates to imaging optics. The illuminator may also include an auxiliary prism optically coupled to the second face of the first prism to correct for astigmatism of the reflected light from the display panel and a beam splitter between the first prism and the auxiliary prism.

Compact near-eye illumination system

A compact and efficient illumination system is provided that is particularly suitable for illuminating a micro display and places the light source within the view of the display. In one embodiment, the illumination system comprises a light source, a package for the light source having a reflective surface on at least one side of the light source, and a diffuser opposite the reflective surface in direct view of the light source. The invention further comprises a film stack to receive light through the diffuser, the film stack transmitting light within a maximum exit angle and reflecting substantially all other light to the diffuser.
