Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
218 words
A system for generating light images of various colors comprising laser means for generating a single light beam capable of being separated into a plurality of different color light beams, first prism means for producing as an output a plurality of different color light beams from said single light beam, first mirror means for directing said single light beam on said first prism means, second prism means for collimating the output of said first prism means to produce as output a plurality of different color light beams having spaced parallel paths, a plurality of spaced aligned moveably x-y mirror means each respectively moving a light beam thereon in a manner to describe a desired pattern, second mirror means positioned for directing said output of said second prism means along a path parallel to a line defined by said spaced, aligned, moveable x-y mirror means, a plurality of third mirror means respectively positioned in said path adjacent said plurality of moveable x-y mirror means for directing a different one of said collimated different color light beams onto a different one of said moveable x-y mirror means, and beam torquer means for reciprocally moving the light beams directed at said second mirror means whereby each of the patterns described by said moveable x-y mirror means is made to change color.
Claim 2
Independent Claim
218 words
A system for generating light images of various colors comprising laser means for generating a single light beam capable of being separated into a plurality of different color light beams, first prism means for producing as an output a plurality of different color light beams from said single light beam, first mirror means for directing said single light beam on said first prism means, second prism means for collimating the output of said first prism means to produce as output a plurality of different color light beams having spaced parallel paths, a plurality of spaced aligned moveably x-y mirror means each respectively moving a light beam thereon in a manner to describe a desired pattern, second mirror means positioned for directing said output of said second prism means along a path parallel to a line defined by said spaced, aligned, moveable x-y mirror means, a plurality of third mirror means respectively positioned in said path adjacent said plurality of moveable x-y mirror means for directing a different one of said collimated different color light beams onto a different one of said moveable x-y mirror means, and beam torquer means for reciprocally moving the light beams directed at said second mirror means whereby each of the patterns described by said moveable x-y mirror means is made to change color.
Claim 3
Dependent Claim
44 words
A system for generating light images as specified in claim 1 where in said beam torquer means is positioned between said first and second prism means for directing the different color light beam output of said first prism means onto said second prism means.
Claim 4
Dependent Claim
28 words
A system as recited in claim 2 wherein said beam torquer means includes a beam torquer mirror, and motor means for reciprocally moving said beam and torquer mirror.
Claim 5
Dependent Claim
59 words
A system as recited in claim 3 wherein there is included, a source of signals for actuating said motor means, and means for applying signals from said source to said plurality of moveable x-y mirror means for compensating for any adverse effects created in the light patterns created as a result of reciprocal motion of said beam torquer mirror.
Claim 6
Dependent Claim
104 words
A system as recited in claim 1 wherein said second mirror means includes a fifty percent reflecting mirror means for directing fifty percent of the light of the collimated different color light beams along said path and passing therethrough the remainder of said light, a one hundred percent reflecting mirror means for directing one hundred percent of the light of the collimated different color light beams along said path, and means for selectively positioning either said fifty percent reflecting mirror means, or said one hundred percent reflecting mirror means, or neither, to intercept and direct said collimated different color light beams along said path.
Claim 7
Dependent Claim
113 words
A system as recited in claim 5 wherein there is included a plurality of spaced translucent light interference wheel means, a motor means for rotating each of said plurality of spaced translucent light interference wheel means, fourth mirror means positioned for receiving the light passed by said second mirror means and redirecting it along a path parallel to said plurality of spaced translucent light interference means, and a plurality of selectively moveable fifth mirror means positioned adjacent said path parallel to said spaced translucent light interference means for selectively intercepting and redirecting said collimated different color light beams or one of said plurality of spaced translucent light interference wheel means to pass therethrough.
Claim 8
Dependent Claim
53 words
A system as recited in claim 1 wherein there is included a plurality of selectively actuatable shutter means each positioned before and to one side of each of said plurality of third mirror means for preventing interception of one of said collimated different color light beams by one of said third mirror means.
Claim 9
Dependent Claim

Claim 10
Dependent Claim
45 words
A system as recited in claim 1 including, rotably mounted diffraction grating means, means for rotating said rotatably mounted diffraction grating means, moveable sixth mirror means for intercepting and redirecting said single light beam, when actuated, to pass through said rotatably mounted diffraction grating means.
Claim 11
Independent Claim
264 words
A method of generating multi-colored light images from a laser which produces light capable of being split up into a plurality of different color light beams comprising: producing a plurality of different color light beams from said laser output, including directing said laser output at prism means for obtaining a plurality of collimated different color light beams, directing each different color light beam at a different set of x-y axis movable mirror means including, directing the plurality of collimated different color light beams along the path adjacent to the location of said plurality of sets of x-y movable mirror means, and successively intercepting a different one of said different color light beams in said path and directing the intercepted beam at a different one of said plurality of sets of x-y axis movable mirror means, moving each set of x-y axis movable mirror means in a predetermined manner to cause the light beam reflected therefrom to describe a desired image, and changing the color of the light beam directed at each set of x-y axis movable mirror means while the set is describing a desired image, to produce a multiple color image, including moving the plurality of different color collimated light beams in a manner to cause interception and direction of one or more color light beams, each of which is directed at one of the plurality of sets of x-y mirror means which thereby intercepts and directs a color light beam which is of different color than the color light beam intercepted when said plurality of collimated different color light beams are stationary.
