Rotating disk of lenses
View Patent ↗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.
1. A rotating lens disk, comprising:
a circular disk having at least one surface;
a sensor detectable indication on the at least one surface;
an outer-most lens affixed to the at least one surface; and
a plurality of next lenses affixed to the at least one surface, each next lens affixed having an offset from an adjacent lens such that the outermost lens and the plurality of next lenses form a single circuit of the disk in a spiral pattern beginning at the outermost lens,
wherein each next lens is offset slightly lower than the previous lens.
2. The disk rotating lens disk of claim 1 wherein the sensor detectable indication is a mirror for indicating a fixed point on the disk.
3. The rotating lens disk of claim 1 wherein the sensor detectable indication is a magnet for indicating a fixed point on the disk.
4. The rotating lens disk of claim 1 where a motor mechanism connected to the disk at a center of the disk, said motor for causing the disk to rotate.
5. A beam delivery system comprising:
a sensor detectable indication affixed to a rotating surface for indicating a fixed point on the rotating surface;
an outer-most lens affixed to the rotating surface;
a plurality of next lenses affixed to the rotating surface, each next lens affixed having an offset from an adjacent lens such that the outermost lens and the plurality of next lenses form a diagonal line in relation to an edge of the rotating surface beginning at the outermost lens;
said rotating surface moving at a constant speed in a direction along the edge of the surface such that the diagonal line of lenses move past in succession;
a stationary beam source configured to transmit a beam through the lenses as the lenses are moved through the beam;
said beam synchronized with the rotating surface using the fixed point;
whereby each lens is configured to bend the beam such that the beam moves across a projection surface.
6. The beam delivery system of claim 5 wherein each next lens is offset slightly lower than the previous lens.
7. The beam delivery system of claim 5 where the edge of the rotating surface is a circumference of a cylinder.
8. The beam delivery system of claim 5 where the beam is a beam of light.
9. The beam delivery system of claim 5 where the beam is generated by a laser.
