Abstract
Abstract An optical projection device is provided with means to create and vary a light image. The image can be varied in form, number, color, attitude, focus, and illumination intensity. The image can be caused to move about and caused to vibrate in intensity. Each of the image variables is controlled by a keyboard such that a particular image status can be recalled by proper key manipulation. The resulting image variations are useful as a form of artistic expression.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
191 words
An optical image projecting system for projecting an image having a plurality of variables under the keyboard control of an operator comprising; a source of light, means to collect the light into a beam, a control keyboard, means controlled by said keyboard to cyclically vary the intensity of the light, means to form a projectable image comprising a device to randomly deflect and distort the beam of light in a manner dependent upon the relative position of said device with respect to said light beam and means controlled by said keyboard to position said device, filter means for placement in the path of the projectable image, said filter means comprising color filter material having areas which differ in color and intensity from other areas and keyboard controlled means to change is position of the filter material in said path, a lens system to focus and project the light which forms the projectable image, and keyboard controlled positioning means connected to a pair of relatively positionable reflective surfaces located in the path of the projected image to direct the projected image in response to the keyboard controlled position of the reflective surfaces.
Claim 2
Dependent Claim
191 words
An optical image projecting system for projecting an image having a plurality of variables under the keyboard control of an operator comprising; a source of light, means to collect the light into a beam, a control keyboard, means controlled by said keyboard to cyclically vary the intensity of the light, means to form a projectable image comprising a device to randomly deflect and distort the beam of light in a manner dependent upon the relative position of said device with respect to said light beam and means controlled by said keyboard to position said device, filter means for placement in the path of the projectable image, said filter means comprising color filter material having areas which differ in color and intensity from other areas and keyboard controlled means to change is position of the filter material in said path, a lens system to focus and project the light which forms the projectable image, and keyboard controlled positioning means connected to a pair of relatively positionable reflective surfaces located in the path of the projected image to direct the projected image in response to the keyboard controlled position of the reflective surfaces.
Claim 3
Dependent Claim
20 words
The image projecting system of claim 1 wherein means which form the projectable image comprise a transparent randomly faceted crystal.
Claim 4
Dependent Claim
42 words
The image projecting system of claim 1 wherein the means which cyclically vary the intensity of the light comprises at least two oppositely rotating vanes of opaque material which cooperate to repetitively block and unblock the light beam as the vanes rotate.
Claim 5
Dependent Claim
29 words
The image projecting system of claim 3 wherein the peripheries of the vanes are configured such that apertures of variable size and location are formed as the vanes rotate.
Claim 6
Dependent Claim
59 words
The image projecting system of claim 1 wherein the filter means comprises a wheel of color filter material which varies in color circumferentially of the wheel and in color intensity radially of the wheel, and the means to change the position of the filter material comprises means to rotatably move the wheel and means to radially move the wheel.
Claim 7
Dependent Claim
19 words
The image projecting system of claim 1 wherein means are provided to vary the overall intensity of the image.
Claim 8
Dependent Claim
22 words
The image projecting system of claim 1 wherein means are provided to control the focus of the lens system from the keyboard.
Claim 9
Dependent Claim
67 words
The image projecting system of claim 1 wherein one of the reflective surfaces comprises a plurality of adjacent mirror segments attached to a flexible support member such that the angular relationship of the mirror segments can be varied by flexure of the flexible member and means are provided to control said flexure from said keyboard whereby the projected image is divided into a plurality of similar images.
Claim 10
Dependent Claim
37 words
The image projecting system of claim 1 wherein one of the reflective surfaces is mounted so as to revolve about the optical axis and with respect to the other mirror so as to revolve the projected image.
