Abstract
Abstract The disclosure relates to a three dimensional color display wherein controlled modulated laser light of predetermined different frequencies is transmitted via fiber optics and combined in a fiber optic coupler to provide a combined light beam. This light beam is transmitted along a fiber optic path wherefrom it is collimated and a three dimensional color display is formed therefrom. The three dimensional display is provided by an x-y scanner for forming a two dimensional image from the light on the single fiber optic path, a rotating display screen for causing each point on the two dimensional image to move along a path making an acute angle with the two dimensional image wherein operation of one of the scanner and the rotating display screen is controlled relative to the other.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
201 words
A color display system comprising: (a) a plurality of light sources, each of different predetermined frequency; (b) light modulating means associated with each said light source for continually and variably controlling the intensity of light of each of said predetermined frequency; (c) fiber optic means for receiving said light of said predetermined frequencies from said light modulating means along individual paths coupled to said light modulating means, combining said received light from each said path and transmitting said combined light along a single fiber optic path; and (d) display means for receiving said combined light transmitted along said single fiber optic path to provide a three dimensional image of the light transmitted along said single fiber optic path of a color determined by the intensity of each of the light sources as controlled by the light modulating means, said display means providing a three dimensional display including: (e) scanning means forming and projecting therefrom a two dimensional image from said light on said single fiber optic path, (f) a generally flat display screen substantially defining a plane, and (g) means for rotating the generally flat display screen about an axis of rotation passing obliquely through said plane of said display screen.
Claim 2
Dependent Claim
201 words
A color display system comprising: (a) a plurality of light sources, each of different predetermined frequency; (b) light modulating means associated with each said light source for continually and variably controlling the intensity of light of each of said predetermined frequency; (c) fiber optic means for receiving said light of said predetermined frequencies from said light modulating means along individual paths coupled to said light modulating means, combining said received light from each said path and transmitting said combined light along a single fiber optic path; and (d) display means for receiving said combined light transmitted along said single fiber optic path to provide a three dimensional image of the light transmitted along said single fiber optic path of a color determined by the intensity of each of the light sources as controlled by the light modulating means, said display means providing a three dimensional display including: (e) scanning means forming and projecting therefrom a two dimensional image from said light on said single fiber optic path, (f) a generally flat display screen substantially defining a plane, and (g) means for rotating the generally flat display screen about an axis of rotation passing obliquely through said plane of said display screen.
