Abstract
A display system includes an illumination source configured to produce visible and nonvisible radiation and to direct the visible and nonvisible radiation along an optical path; and a modulator disposed in the optical path configured to modulate the visible radiation to generate a visible image, and to modulate the nonvisible radiation to generate a nonvisible data stream.
Claims35
A display system comprising:
- an illumination source configured to produce visible and nonvisible radiation;
- and
- a modulator configured to modulate the visible radiation to generate a visible image and to modulate the nonvisible radiation to generate a nonvisible data stream.
A display system comprising:
- an illumination source configured to produce visible and nonvisible radiation;
- and
- a modulator configured to modulate the visible radiation to generate a visible image and to modulate the nonvisible radiation to generate a nonvisible data stream that includes audio data.
A projection engine, comprising:
- at least one illumination source;
- a color-forming element, configured to manipulate radiation from the at least one illumination source to define at least one visible band and at least one nonvisible band;
- and
- an image-forming element configured to form a visible image using the visible band and to form a nonvisible data stream using the nonvisible band.
A method of temporally sequencing a visible image and a nonvisible data stream, the method comprising:
- generating visible and nonvisible radiation;
- sequencing the visible radiation and the nonvisible radiation using a modulator;
- modulating the visible radiation to generate a visible image;
- and
- modulating the nonvisible radiation to generate a nonvisible data stream.
A method of temporally sequencing a visible image and a nonvisible data stream, the method comprising:
- generating visible and nonvisible radiation;
- sequencing the visible radiation and the nonvisible radiation;
- modulating the visible radiation to generate a visible image;
- modulating the nonvisible radiation to generate a nonvisible data stream that includes audio data;
- and
- projecting the nonvisible data stream onto a receiver.
A storage medium readable by a processor, having embodied therein a program of commands executable by the processor to:
- modulate visible radiation to generate a visible image corresponding to received image data;
- and
- modulate nonvisible radiation to generate a nonvisible data stream corresponding to received non-image data.
A display system, comprising:
- means for producing visible radiation;
- means for producing nonvisible radiation;
- means for modulating the visible radiation to generate a visible image;
- and
- means for modulating the nonvisible radiation to generate a nonvisible data stream.
A projector, comprising a projection engine that includes:
- an illumination source that produces visible and nonvisible radiation;
- a color-forming element configured to sequentially pass the visible and nonvisible radiation;
- an image-forming element configured to receive the sequenced visible and nonvisible radiation, form a visible image using the visible radiation, and form a nonvisible data stream using the nonvisible radiation.
