Claims
- 1. A light shape altering device, having elements which selectively modify light, located in the path of a light beam and comprising:a controller which obtains a desired shape for a colored beam of light, and converts said shape into control signals indicative of color components of both said desired shape and colors; a first controllable light reflection device, receiving at least part of said control signal, having a plurality of controllable elements, each element defining a portion of an image, and each element being separately controllable between a first state which passes light to a desired object of illumination and a second state which reflects light away from the desired object of illumination; and a second controllable light reflection device, receiving at least part of said control signal, having a plurality of controllable elements, each element defining a portion of an image, and each element being separately controllable between a first state which passes light to a desired object of illumination and a second state which reflects light away from the desired object of illumination.
- 2. A device as in claim 1, wherein said light reflection devices are digital mirror devices.
- 3. A device as in claim 1, wherein said controller produces multiple signals, one of which is applied to said first light reflection device, and a second of which is applied to said second light reflection device.
- 4. A device as in claim 1, further comprising a third light reflection device.
- 5. A device as in claim 1, wherein said first, second and third light reflection devices respectively are controlled for red, green and blue components of the signal.
- 6. A device as in claim 1, wherein said first, second and third light reflection devices respectively are controlled for cyan, magenta, yellow components of the signal.
- 7. A light shape altering device, comprising:a controller, producing information indicative of a plurality of color components for a desired shaped light beam; and a plurality of selectively direction-reflecting devices, respectively receiving said information indicative of said components, each of said selectively direction-reflecting devices selectively passing different light, depending on said color components.
- 8. A device as in claim 7, wherein said direction reflecting devices are digital micromirrors.
- 9. A device as in claim 7, wherein there are three of said selectively direction-reflecting devices, each of which receives light over a different light path.
- 10. A device as in claim 7, further comprising an image memory, storing an image whose contents are used by the controller to produce said plurality of color components.
- 11. A mirror gobo, comprising:a light source producing at least two separated color components; at least two electrically pixel-level controllable devices, which are electrically controlled to change position, a first of said devices being optically in series with a first of said color components, and a second of said devices being in series with a second of said color components.
- 12. A mirror gobo as in claim 11 further comprising a light splitter for said light source, splitting an output of said light source into multiple color components.
