Projector provided with a plurality of image generators
First Claim
1. A projector having;
- means for supplying first and second radiation beams;
first image generating means for modulating a plurality of portions of said first radiation beam individually and forming a diffused beam and a non-diffused beam to generate a first image;
second image generating means for modulating a plurality of portions of said second radiation beam individually and forming a diffused beam and a non-diffused beam to generate a second image, said second image generating means being provided next said first image generating means; and
means for projecting said first and second images onto a predetermined plane by the use of one of said diffused beams and said non-diffused beams from said first and second image generating means, said first and second image generating means being designed such that said diffused beams have a rotation-asymmetric orientation characteristic, to direct most of said diffused beams from one of said generating means in a direction different from the direction toward the other generating means.

Abstract
A projector has means for supplying first and second radiation beams, first image generating means for modulating a plurality of portions of the first radiation beam individually and forming a deflected beam and a non-deflected beam to generate a first image, second image generating means for modulating a plurality of portions of the second radiation beam individually and forming a deflected beam and a non-deflected beam to generate a second image, and means for projecting the first and second images onto a predetermined plane by the use of one of the deflected beams and the non-deflected beams from the first and second image generating means, the first and second image generating means emitting the deflected beams so that most of the deflected beam from one of the generating means may substantially not enter the other generating means.

10. A projector comprising;
-
means for supplying radiation beams; image generating means for modulating a plurality of portions of said radiation beams individually to form diffused beams and non-diffused beams to generate said images; and means for projecting said images onto a predetermined plane by the use of one of said diffused beams and non-diffused beams from said image generating means, wherein said diffused beams by way of said image generating means are designed so to have a rotation-asymmetric orientation characteristic. - View Dependent Claims (11)

12. A projector having;
-
means for supplying first and second radiation beams; first image generating means for modulating a plurality of portions of said first radiation beam individually and forming a deflected beam and a non-deflected beam to generate a first image; second image generating means for modulating a plurality of portions of said second radiation beam individually and forming a deflected beam and a non-deflected beam to generate a second image; and
p1 means for projecting said first and second images onto a predetermined plane by the use of one of said deflected beams and said non-deflected beams from said first and second image generating means, said first and second image generating means emitting said deflected beams so that most of said deflected beam from one of said generating means may substantially not enter the other generating means;wherein said first and second image generating means transmit said portions of said first and second radiation beams, respectively, therethrough.

13. A projector having;
-
means for supplying first and second radiation beams; first image generating means for modulating a plurality of portions of said first radiation beam individually and forming a deflected beam and a non-deflected beam to generate a first image; second image generating means for modulating a plurality of portions of said second radiation beam individually and forming a deflected beam and a non-deflected beam to generate a second image; and
p1 means for projecting said first and second images onto a predetermined plane by the use of one of said deflected beams and said non-deflected beams from said first and second image generating means, said first and second image generating means emitting said deflected beams so that most of said deflected beam from one of said generating means may substantially not enter the other generating means;wherein said first and second image generating means diffuse said portions of said first and second radiation beams, respectively, to thereby form said deflected beams; wherein said first and second image generating means diffract said portions of said first and second radiation beams, respectively, to thereby diffuse the same.
