Abstract

A display system includes a waveguide optical panel having an inlet face and an opposite outlet face. An image beam is projected across the inlet face laterally and transversely for display on the outlet face. An optical detector including a matrix of detector elements is optically aligned with the inlet face for detecting a corresponding lateral and transverse position of an inbound light spot on the outlet face.

Interactive display system having a digital micromirror imaging device

Patent Veligdan, James T.; DeSanto, Leonard; Kaull, Lisa; ...

A display system includes a waveguide optical panel having an inlet face and an opposite outlet face. A projector cooperates with a digital imaging device, e.g. a digital micromirror imaging device, for projecting an image through the panel for display on the outlet face. The imaging device includes an array of mirrors tiltable between opposite display and divert positions. The display positions reflect an image light beam from the projector through the panel for display on the outlet face. The divert positions divert the image light beam away from the panel, and are additionally used for reflecting a probe lightmore » « less

Interactive display system having a scaled virtual target zone

Patent Veligdan, James T.; DeSanto, Leonard

A display system includes a waveguide optical panel having an inlet face and an opposite outlet face. A projector and imaging device cooperate with the panel for projecting a video image thereon. An optical detector bridges at least a portion of the waveguides for detecting a location on the outlet face within a target zone of an inbound light spot. A controller is operatively coupled to the imaging device and detector for displaying a cursor on the outlet face corresponding with the detected location of the spot within the target zone.

System for outputting a spectrum of light of a scene having optical detectors to receive light of different spectral transmittance from respective filters

Patent Shields, Eric A.

Technologies pertaining to a compressive sensing snapshot spectrometer are described herein. Light is focused through an array of filters onto an array of optical detectors by way of an optical objective. Each detector in the array receives light from a single respective filter in the filters. Each filter in the filters has a spectral transmittance function that overlaps a spectral transmittance function of at least one other filter. A compressive sensing algorithm is executed over outputs of the detectors based upon the known spectral transmittance functions of the filters. Based upon the execution of the compressive sensing algorithm, intensity valuesmore » « less
