Abstract
Abstract An acousto-optic device including an acousto-optic medium having a plurality of closely spaced transducers bonded thereto in a linear array. A signal of the same frequency is supplied to those transducers which are to diffract out or deflect elemental portions of a light beam incident upon the acousto-optic medium to thereby provide a plurality of light spots which can be written in parallel.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
139 words
An optical system including: means for providing a high intensity light beam of large area, an acousto-optic device disposed in the path of said light beam and including an acousto-optic media having a plurality of transducers bonded thereto, each of said transducers having an electrode associated therewith, first means for providing a radio frequency signal, second means coupled to said electrodes and said first means for supplying said radio frequency signal simultaneously to selected of said transducers whereby sound waves are provided within the portions of said media aligned with said selected transducers and portions of said light beam are simultaneously diffracted by said sound waves, and a light sensitive medium disposed to receive simultaneously said portions of said light beam diffracted by said sound waves whereby spots of light are written in parallel on said light sensitive medium.
Claim 2
Dependent Claim
139 words
An optical system including: means for providing a high intensity light beam of large area, an acousto-optic device disposed in the path of said light beam and including an acousto-optic media having a plurality of transducers bonded thereto, each of said transducers having an electrode associated therewith, first means for providing a radio frequency signal, second means coupled to said electrodes and said first means for supplying said radio frequency signal simultaneously to selected of said transducers whereby sound waves are provided within the portions of said media aligned with said selected transducers and portions of said light beam are simultaneously diffracted by said sound waves, and a light sensitive medium disposed to receive simultaneously said portions of said light beam diffracted by said sound waves whereby spots of light are written in parallel on said light sensitive medium.
Claim 3
Dependent Claim
18 words
The system of claim 1 wherein said transducers are disposed in a linear array along said acousto-optic medium.
Claim 4
Dependent Claim
24 words
The system of claim 1 further including means for preventing undiffracted portions of said light beam from being received by said light sensitive medium.
Claim 5
Dependent Claim
168 words
An optical system including: first means for providing a high intensity light beam of large area, an acousto-optic device disposed in the path of said light beam and including an acousto-optic media having a plurality of transducers bonded thereto, each of said transducers having an electrode associated therewith, second means for providing a radio frequency signal, third means coupled to said electrodes and said second means for supplying said radio frequency signal simultaneously to selected to said transducers whereby sound waves are provided within the portions of said media aligned with said selected transducers and portions of said light beam are simultaneously diffracted by said sound waves, a light sensitive medium disposed to receive simultaneously said portions of said light beam diffracted by said sound waves whereby spots of light are written in parallel on said light sensitive medium, and fourth means disposed between said acousto-optic device and said light sensitive medium for preventing undiffracted portions of said light beam from being received by said light sensitive medium.
Claim 6
Dependent Claim
168 words
An optical system including: first means for providing a high intensity light beam of large area, an acousto-optic device disposed in the path of said light beam and including an acousto-optic media having a plurality of transducers bonded thereto, each of said transducers having an electrode associated therewith, second means for providing a radio frequency signal, third means coupled to said electrodes and said second means for supplying said radio frequency signal simultaneously to selected to said transducers whereby sound waves are provided within the portions of said media aligned with said selected transducers and portions of said light beam are simultaneously diffracted by said sound waves, a light sensitive medium disposed to receive simultaneously said portions of said light beam diffracted by said sound waves whereby spots of light are written in parallel on said light sensitive medium, and fourth means disposed between said acousto-optic device and said light sensitive medium for preventing undiffracted portions of said light beam from being received by said light sensitive medium.
