    摘要: PCT No. PCT/GB93/01700 Sec. 371 Date Feb. 14, 1995 Sec. 102(e) Date Feb. 14, 1995 PCT Filed Aug. 11, 1993 PCT Pub. No. WO94/04951 PCT Pub. Date Mar. 3, 1994A transparency intended for use in a high intensity light beam projector for stage lighting purposes, comprises a glass substrate (10) having selected areas (11) thereof coated with a multi-layer dielectric coating forming a dichroic color filter. Selective coating is effected either by removing parts of an overall multi-layer coating through a mask, or by applying the multi-layer coating selectively through a mask.

    摘要: An illumination obscurement device for controlling the obscurement of illumination from a light source which is optimized for use with a rectangular, arrayed, selective reflection device. In a preferred embodiment, a rotatable shutter (500) with three positions (504,510,516) is placed between a light source (602) and a DMD (604). The first position of the shutter is a mask (504), preferably an out of focus circle. This out of focus circle creates a circular mask and changes any unwanted dim reflection to a circular shape. The second position of the shutter is completely open (510), allowing substantially all the light to pass. The third position of the shutter is completely closed (514), blocking substantially all the light from passing. By controlling the penumbra illumination surrounding the desired illumination, DMDs (604) can be used in illumination devices without creating undesirable rectangular penumbras (628).

    摘要: A digital micromirror device ("DMD") is used to alter the shape of light that is projected onto a stage. The DMD selectively reflects some light, thereby shaping the light that is projected onto the stage. The control for the alteration is controlled by an image. That image can be processed, thereby carrying out image processing effects on the shape of the light that is displayed.
