Abstract
Abstract Apparatus for directing a light beam in a desired direction without moving the light source. An optical system is disclosed, including a laser and a linearly translatable optical device for directing or orienting a beam from the laser. The optical directional device includes a series of mirrors arranged to successively reflect the laser beam and further includes structure for rotating the mirrors about various axes to allow exiting of the laser beam from the last of these mirrors in a desired direction. The laser system is particularly useful in the process of photocoagulation and is useful in other medical and optical applications as well.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
74 words
A laser system of a type capable of use in a photocoagulator including a laser and linearly translatable directional means for directing a primary beam from said laser, said directional means comprising: a supporting structure; a series of mirrors supported by said structure, said mirrors arranged to successively reflect said beam; and, orienting means for orienting said mirrors to allow exiting of said beam from the last of said mirrors in a desired direction.
Claim 2
Dependent Claim
74 words
A laser system of a type capable of use in a photocoagulator including a laser and linearly translatable directional means for directing a primary beam from said laser, said directional means comprising: a supporting structure; a series of mirrors supported by said structure, said mirrors arranged to successively reflect said beam; and, orienting means for orienting said mirrors to allow exiting of said beam from the last of said mirrors in a desired direction.
Claim 3
Dependent Claim
90 words
A system as recited in claim 1 wherein said series of mirrors further comprises: a first mirror supported by said structure said first mirror arranged to reflect said primary beam incident thereupon providing a first reflected beam; a second mirror supported by said structure, said second mirror arranged to reflect said first reflected beam incident thereupon, providing a second reflected beam; and a third mirror supported by said structure, said third mirror arranged to reflect said second reflected beam incident thereupon, providing a third reflected beam exiting from said system.
Claim 4
Dependent Claim
60 words
A system as recited in claim 2 wherein said orienting means comprises means for simultaneously rotating said second mirror and orbiting said third mirror about an axis parallel to said first reflected beam, and for independently rotating said third mirror about an axis parallel to said second reflected beam, whereby said exiting third beam is pointed in a desired direction.
Claim 5
Dependent Claim
21 words
A system as recited in claim 3 further including a motor wherein said orienting means is operatively connected to said motor.
Claim 6
Dependent Claim
49 words
A system as recited in claim 2 wherein said second mirror is arranged to angularly displace said second reflected beam by substantially 90* from said first reflected beam and said third mirror is arranged to angularly displace said third reflected beam by substantially 90* from said second reflected beam.
Claim 7
Dependent Claim
22 words
A system as recited in claim 2 wherein said first reflected beam is angularly displaced from said primary beam by substantially 90*.
Claim 8
Dependent Claim
22 words
A system as recited in claim 2 wherein said first mirror is displaced from said second mirror by a first selectable distance.
Claim 9
Dependent Claim
22 words
A system as recited in claim 2 wherein said first mirror is displaced from said third mirror by a second selectable distance.
Claim 10
Dependent Claim
19 words
A system as recited in claim 1 wherein said structure is made of material transparent to said primary beam.
