Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
142 words
AN OPTICAL SYSTEM FOR PROJECTING LIGHT FROM A SOURCE OF LIGHT TO AN IMAGE AREA IN ACCORDANCE WITH DEVIATION OF THE LIGHT PRODUCED BY A LIGHT MODULATING MEDIUM COMPRISING A LIGHT MASK INCLUDING AN ARRAY OF ALTERNATELY OPAQUE AND TRANSPARENT AREAS INTERPOSED BETWEEN SAID LIGHT SOURCE AND SAID MODULATING MEDIUM, A FIRST ARRAY OF CONVERGING LENSES INTERPOSED BETWEEN SAID LIGHT SOURCE AND SAID LIGHT MASK FOR IMAGING SAID SOURCE IN SAID TRANSPARENT AREAS, A SECOND ARRAY OF CONVERGING LENSES INTERPOSED BETWEEN SAID FIRST ARRAY OF LENSES AND SAID MASK FOR IMAGING EACH LENS OF SAID FIRST ARRAY ON A COMMON AREA OF SAID MEDIUM AND MASKING MEANS INTERPOSED BETWEEN SAID MEDIUM AND THE IMAGE AREA FOR BLOCKING LIGHT EMANATING FROM AND UNDEVIATED BY SAID MEDIUM AND SELECTIVELY PASSING LIGHT EMANATING FROM SAID MEDIUM IN ACCORDANCE WITH THE DIFFRACTION THEREOF BY SAID MEDIUM.
Claim 2
Dependent Claim
142 words
AN OPTICAL SYSTEM FOR PROJECTING LIGHT FROM A SOURCE OF LIGHT TO AN IMAGE AREA IN ACCORDANCE WITH DEVIATION OF THE LIGHT PRODUCED BY A LIGHT MODULATING MEDIUM COMPRISING A LIGHT MASK INCLUDING AN ARRAY OF ALTERNATELY OPAQUE AND TRANSPARENT AREAS INTERPOSED BETWEEN SAID LIGHT SOURCE AND SAID MODULATING MEDIUM, A FIRST ARRAY OF CONVERGING LENSES INTERPOSED BETWEEN SAID LIGHT SOURCE AND SAID LIGHT MASK FOR IMAGING SAID SOURCE IN SAID TRANSPARENT AREAS, A SECOND ARRAY OF CONVERGING LENSES INTERPOSED BETWEEN SAID FIRST ARRAY OF LENSES AND SAID MASK FOR IMAGING EACH LENS OF SAID FIRST ARRAY ON A COMMON AREA OF SAID MEDIUM AND MASKING MEANS INTERPOSED BETWEEN SAID MEDIUM AND THE IMAGE AREA FOR BLOCKING LIGHT EMANATING FROM AND UNDEVIATED BY SAID MEDIUM AND SELECTIVELY PASSING LIGHT EMANATING FROM SAID MEDIUM IN ACCORDANCE WITH THE DIFFRACTION THEREOF BY SAID MEDIUM.
Claim 3
Dependent Claim
106 words
AN OPTICAL SYSTEM COMPRISING A SMALL SOURCE OF LIGHT, AN ELLIPTICAL REFLECTOR FOR IMAGING SAID SOURCE ON AN AREA TO BE ILLUMINATED, A LIGHT MASK INCLUDING AN ARRAY OF ALTERNATING OPAQUE AND TRANSPARENT AREAS INTERPOSED BETWEEN SAID SOURCE AND REFLECTOR AND SAID AREA, A FIRST ARRAY OF LATERALLY DISPOSED CONVERGING LENSES INTERPOSED BETWEEN SAID LIGHT SOURCE AND SAID LIGHT MASK FOR IMAGING SAID SOURCE IN SAID TRANSPARENT AREAS, A SECOND ARRAY OF LATERALLY DISPOSED CONVERGING LENSES INTERPOSED BETWEEN SAID FIRST ARRAY OF LENSES AND SAID MASK, EACH LENS OF SAID SECOND ARRAY IMAGING A RESPECTIVE ONE OF THE LENSES OF SAID FIRST ARRAY ON SAID AREA.
Claim 4
Dependent Claim
106 words
AN OPTICAL SYSTEM COMPRISING A SMALL SOURCE OF LIGHT, AN ELLIPTICAL REFLECTOR FOR IMAGING SAID SOURCE ON AN AREA TO BE ILLUMINATED, A LIGHT MASK INCLUDING AN ARRAY OF ALTERNATING OPAQUE AND TRANSPARENT AREAS INTERPOSED BETWEEN SAID SOURCE AND REFLECTOR AND SAID AREA, A FIRST ARRAY OF LATERALLY DISPOSED CONVERGING LENSES INTERPOSED BETWEEN SAID LIGHT SOURCE AND SAID LIGHT MASK FOR IMAGING SAID SOURCE IN SAID TRANSPARENT AREAS, A SECOND ARRAY OF LATERALLY DISPOSED CONVERGING LENSES INTERPOSED BETWEEN SAID FIRST ARRAY OF LENSES AND SAID MASK, EACH LENS OF SAID SECOND ARRAY IMAGING A RESPECTIVE ONE OF THE LENSES OF SAID FIRST ARRAY ON SAID AREA.
