Abstract
A device for projecting images from a video generating device such as a computer, television receiver, or similar device onto a screen or other surface is described in this invention. The device uses a rotating disk containing numerous lenses to direct a light beam from a laser or other light source towards the screen. In one embodiment, a pulsed laser light from red, green, and blue lasers are combined into a single light pulse that is transmitted through the rotating disk that transmit each light pulse to a specific location on the screen.
Claims35
A light beam delivery system for delivering a beam of light across a surface comprising
- a source for a beam of light,
- said beam of light sent through a rotating disk where the rotating disk contains a multitude of lenses, such that the lenses are aligned to direct the beam of light across the surface.
A method of delivering a beam of light across a surface comprising
- generation of a beam of light,
- transmitting said beam of light sent through a rotating disk where the rotating disk contains a multitude of lenses, such that the lenses are aligned to direct the beam of light across the surface.
An apparatus for the delivery of an image to a surface comprising an electronic representation of the image;
- a processing mechanism to transform the image into pulses of light;
- said pulses of light transmitted through a rotating disk of a multitude of lenses, wherein the pulses of light are synchronized with the rotating disk such that the pulses of light form a visible representation of the image on the surface.
A light projecting device comprising
- an interface for connecting the light projecting device to a video generating device;
- said interface receiving instructions from the video generating device that specify a video image;
- said instructions reformatted by the light projecting device into instructions for activating one or more semiconductor lasers, said lasers energized and de-energized to form pulses of light,
- said pulses of light sent through a rotating disk,
- such that the video image is projected from the light projecting device in a format such that the video image is visible on a surface.
A method of delivering a beam of light across a surface comprising
- generating a beam of light using one or more semiconductor lasers,
- said beam of light consisting of a stream of pulses of light to display on the surface,
- transmitting said pulses of light through a rotating disk;
- and
- synchronizing said rotating disk with the lasers such that the pulses of light are modified such that an image is formed on the surface.
An apparatus for the delivery of an image to a surface comprising
- an electronic representation of the image;
- a processing mechanism to transform the image into pulses of light using one or more semiconductor lasers;
- said pulses of light transmitted through a rotating disk, wherein the pulses of light are synchronized with the rotating disk such that the pulses of light form a visible representation of the image on the surface.
