Underwater projection
A projection apparatus for projection in a liquid environment comprises a projection surface adapted to be positioned in the liquid environment and a projector adapted to be positioned in the liquid environment. The projector is adapted to project an image on the projection surface.
1. An image projection system, the image projection system comprising:
a liquid media; and
a projection surface comprising a projection screen positioned in the liquid media, wherein the projection screen includes a liquid crystal microdroplet (LCMD) device being switchable between a clear state and an opaque state in response to an electric voltage and being positioned in the liquid media; and
a video projector positioned in the liquid media, wherein the video projector is adapted to project a video image on the projection surface.
2. The image projection system of claim 1 further comprising a liquid-proof projector enclosure wherein the projector enclosure is sized and configured to contain the projector.
3. The image projection system of claim 2 wherein the liquid-proof projector enclosure includes a transparent wall.
4. The image projection system of claim 2 further comprising a heat dissipation system adapted to dissipate heat generated by the projector.
5. The image projection system of claim 4 , wherein the heat dissipation system comprises a blower and exhaust tubing coupled to the liquid-proof projector enclosure.
6. The image projection system of claim 4 , wherein the heat dissipation system includes a corrugated high surface box forming the liquid-proof projector enclosure.
7. The projection apparatus of claim 6 , wherein the corrugated high surface box includes a heat conductive material.
8. The image projection system of claim 1 wherein the projector includes a liquid-proof outer casing.
9. The image projection system of claim 1 wherein the projector includes a liquid-proof shell.
10. The image projection system of claim 1 wherein the projector includes a cooling system adapted to conduct heat through a shell of the projector into the liquid environment.
11. The image projection system of claim 1 wherein the projector includes a water cooling system.
12. The image projection system of claim 1 wherein the projector is battery operated.
13. A method of projecting an image in a liquid media, the method comprising:
providing a projection surface positioned in the liquid media, the projection surface comprising a projection screen, the projection screen including a liquid crystal microdroplet (LCMD) device being switchable between a clear state and an opaque state in response to an electric voltage and positioned in the liquid media;
providing a video projector positioned in the liquid media; and
projecting an video image from the video projector to the projection surface through the liquid media.
14. The method of claim 13 further comprising:
containing the projector in a liquid-proof projector enclosure, wherein projecting the image includes projecting through the projector enclosure.
15. The method of claim 13 further comprising:
dissipating heat away from the projector.
16. The method of claim 13 further comprising:
conducting a flow of water from the projector toward the liquid media to dissipate heat from the projector.
17. The method of claim 13 further comprising:
containing the projector in a corrugated projector enclosure, wherein projecting the image includes projecting through the projector enclosure.
18. The method of claim 13 wherein the projector is battery-operated.
