Abstract

Catadioptric projection systems, devices and methods, including a lens, an illumination source and a reflector, arranged to pass light through a medium and focus the light onto a surface, with a vibration source disposed proximate the medium to impart frequencies on the medium to effect movement of the medium, which may be oscillations, patterns or other movements. The vibration source may be a transducer, audio speaker. The illumination source includes one or more illuminators that may be configured as one or more LEDs, and passes through the lens and provides illumination from one side of the lens, to direct the illumination of projected light through the medium and onto the reflector surface, where the light is reflected off of the mirror surface and back through the medium, through the lens, and focused onto a surface. The device is configured with control circuitry for operating the transducer and LEDs.

Claims (28)

a) an illumination source;

b) a reflector;

c) a focusing element;

d) a vibration generator;

e) a fluid disposed between the reflector and the focusing element; and

f) control circuitry configured to control one or more, or both of the vibrations and the illumination source;

g) wherein the illumination source is configured to pass through the focusing element, and produce a light output that is directed at the fluid and the reflector; and

h) wherein the focusing element is disposed to receive reflected light reflected by the reflector and which passes through the fluid, and focus the light onto a surface.

2 . The catadioptric projection device of claim 1 , wherein the reflector comprises a curved mirror.

3 . The catadioptric projection device of claim 2 , wherein the curved mirror is a parabolic mirror.

4 . The catadioptric projection device of claim 3 , wherein the curved mirror has a center that is the vertex, and wherein the illumination source is disposed above the vertex.

The catadioptric projection device of claim 1 , wherein the reflector comprises a curved mirror, wherein the focusing element comprises a lens, and wherein the lens has a first planar surface and a second surface that is a convex surface, and wherein the illumination source includes an illuminator, and wherein the illuminator is positioned to produce illumination at or after the plane of the first planar surface.

6 . The catadioptric projection device of claim 5 , wherein the illuminator comprises one or more LEDs.

7 . The catadioptric projection device of claim 1 , wherein the illuminator includes one or more components that produce light of a plurality of colors, wherein the control circuitry is configured to control the illumination source to produce strobing of the light.

8 . The catadioptric projection device of claim 1 , wherein the vibration generator comprises a transducer and produces cymatic movement of the fluid, and wherein the illumination source light is reflected off of the reflector through the fluid to light representing the cymatic movement induced in the fluid by the transducer, and wherein the projector projects cymatic images corresponding to the fluid movement.

9 . The catadioptric projection device of claim 8 , wherein the cymatic movement comprises cymatic patterns, and wherein the control circuitry is configured to strobe the illumination source to produce colored light strobing in relation to the cymatic patterns.

10 . The catadioptric projection device of claim 9 , wherein the cymatic image projected has an illusion of movement.

11 .
