Abstract
Abstract A system for producing a two-dimensional multiple line display by scanning a single source or a plurality of linearly arrayed sources with a first rotating or nutating reflective element to reflect the single source or the plurality of independent sources across a screen to produce a display consisting of a single line array in the case of a single source or a band of lines in the case of a plurality of sources. A second rotating or nutating reflective element is employed to reflect the display on the screen to produce a two-dimensional multiple line image of the single line display or a two-dimensional multiple band array of the band of lines. 2

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
127 words
An optical scanning system for producing a multiple line two-dimensional array of display points comprising: at least one modulated light source, a display screen having a textured surface for providing a controlled light scattering, a first light deflecting means periodically rotating about an axis for scanning said at least one modulated light from said light source source and deflecting said light in a first linear direction across said display screen to produce a display of at least one row of display spots, and a second light deflecting means periodically rotating about an axis orthogonal to said first deflecting means for scanning said light on said display screen in a second direction to produce a two-dimensional display of spots representative of said at least one modulated light source.
Claim 2
Dependent Claim
127 words
An optical scanning system for producing a multiple line two-dimensional array of display points comprising: at least one modulated light source, a display screen having a textured surface for providing a controlled light scattering, a first light deflecting means periodically rotating about an axis for scanning said at least one modulated light from said light source source and deflecting said light in a first linear direction across said display screen to produce a display of at least one row of display spots, and a second light deflecting means periodically rotating about an axis orthogonal to said first deflecting means for scanning said light on said display screen in a second direction to produce a two-dimensional display of spots representative of said at least one modulated light source.
Claim 3
Dependent Claim
42 words
An optical scanning system according to claim 1 wherein said second light deflecting means is a means for scanning said band of display spots on said display screen to produce a two-dimensional display of spots including a plurality of bands of spots.
Claim 4
Dependent Claim
66 words
An optical scanning system according to claim 1 wherein said at least one modulated light source is a plurality of independently modulated light sources and wherein said first light deflective means is a reflective means for deflecting the light from said plurality of sources across said display screen to produce a display of a plurality of rows of spots to form a band of display spots.
Claim 5
Dependent Claim
43 words
An optical scanning system according to claim 1 wherein said second light deflecting means is a reflecting means for scanning said band of display spots on said display screen to produce a two-dimensional display of spots including a plurality of bands of spots.
Claim 6
Dependent Claim
23 words
An optical scanning system according to claim 3 wherein said first reflective means is a multi-faceted mirror structure rotatable about a central axis.
Claim 7
Dependent Claim
31 words
An optical scanning system according to claim 5 wherein said second reflective means is a mirror structure rotatable about a central axis orthogonal to the axis of said first reflective means.
Claim 8
Dependent Claim
33 words
An optical system according to claim 3 wherein said texture surfaces surface to provide controlled scattering and wherein said texture is formed of a plurality of depressions having one dimension longer than another.
Claim 9
Dependent Claim
13 words
An optical system according to claim 3 wherein said display screen is curved.
