Abstract
Abstract The mechanism for adjusting an axis of a mirror or other optical element comprises three major parts; i.e., a rotational mount, a mirror normal mount and a mirror plane mount. Relative motion of the rotational and normal mounts about a mutual cylindrical axis provides adjustment of the scanner axis in a plane containing the scanner axis and in a direction normal to the mirror. In a similar fashion, relative motion of the normal and plane mounts about a second mutual cylindrical axis provides adjustment of the scanner axis in a plane containing the scanner axis and in a direction parallel to the mirror surface. Careful control of the relative motions mentioned above allows for the independent adjustment of the scanner axis in the mirror plane and mirror normal plane about the center of the scanner mirror. This mechanism when used with each of a pair of mirrors facilitates the alignment of X-Y scanner axes to obtain "character splitting" in COM imagery by allowing minute and independent adjustment of either scanner axis with no mirror translation; thereby insuring perpendicular scanning.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
242 words
A mechanism for effecting alignment of an axis of a mirror or other optical element in first and second perpendicular planes, the mechanism comprising: A first mounting member adapted to be secured in a fixed position, the mounting member having at an end thereof a generally cylindrical end surface generated about a first axis; a second mounting member having a first generally cylindrical end surface slidably engageable in a mating relationship with, and substantially conforming to, the end surface of the first mounting member, the second mounting member having a second generally cylindrical end surface generated about a second axis substantially perpendicular to the first axis, the first and second axes intersecting each other; a third mounting member having a generally cylindrical end surface slidably engageable in a mating relationship with, and substantially conforming to, the second end surface of the second mounting member whereby each of said mounting members is slidably adjustable with respect to the adjacent mounting member along the engaged cylindrical surfaces; and means for supporting the optical element on the third mounting member with its axis perpendicular to and intersecting said first and second axes so that the axis of the optical element can be aligned in a first plane by effecting relative movement between said first and second mounting members and the optical element can be aligned in a second plane perpendicular to said first plane by effecting relative movement between said second and third mounting members.
Claim 2
Dependent Claim
242 words
A mechanism for effecting alignment of an axis of a mirror or other optical element in first and second perpendicular planes, the mechanism comprising: A first mounting member adapted to be secured in a fixed position, the mounting member having at an end thereof a generally cylindrical end surface generated about a first axis; a second mounting member having a first generally cylindrical end surface slidably engageable in a mating relationship with, and substantially conforming to, the end surface of the first mounting member, the second mounting member having a second generally cylindrical end surface generated about a second axis substantially perpendicular to the first axis, the first and second axes intersecting each other; a third mounting member having a generally cylindrical end surface slidably engageable in a mating relationship with, and substantially conforming to, the second end surface of the second mounting member whereby each of said mounting members is slidably adjustable with respect to the adjacent mounting member along the engaged cylindrical surfaces; and means for supporting the optical element on the third mounting member with its axis perpendicular to and intersecting said first and second axes so that the axis of the optical element can be aligned in a first plane by effecting relative movement between said first and second mounting members and the optical element can be aligned in a second plane perpendicular to said first plane by effecting relative movement between said second and third mounting members.
Claim 3
Dependent Claim
209 words
A mechanism for aligning a mirror or other optical element comprising: a first annular member adapted to be rigidly mounted to a support; a second annular member axially aligned with said first annular member; a mounting member axially aligned with said first and second members and including a mounting shaft which extends axially through said first and second members; means associated with said members for urging a surface and said mounting member into engagement with a surface of said second member while urging a surface of said second member into engagement with a surface of said first member; the engaged surfaces of said first member and said second member forming an arcuate portion of a cylinder having a longitudinal axis which is substantially perpendicular to said first direction; the engaged surfaces of said mounting member and said second member forming an arcuate portion of a cylinder having a longitudinal axis which is substantially perpendicular to said second direction; means associated with said first member for adjusting the radial position of said mounting shaft within said first member in a first direction; means associated with said second member for adjusting the radial position of said mounting shaft within said second member in a second direction orthogonal to said first direction.
Claim 4
Dependent Claim
209 words
A mechanism for aligning a mirror or other optical element comprising: a first annular member adapted to be rigidly mounted to a support; a second annular member axially aligned with said first annular member; a mounting member axially aligned with said first and second members and including a mounting shaft which extends axially through said first and second members; means associated with said members for urging a surface and said mounting member into engagement with a surface of said second member while urging a surface of said second member into engagement with a surface of said first member; the engaged surfaces of said first member and said second member forming an arcuate portion of a cylinder having a longitudinal axis which is substantially perpendicular to said first direction; the engaged surfaces of said mounting member and said second member forming an arcuate portion of a cylinder having a longitudinal axis which is substantially perpendicular to said second direction; means associated with said first member for adjusting the radial position of said mounting shaft within said first member in a first direction; means associated with said second member for adjusting the radial position of said mounting shaft within said second member in a second direction orthogonal to said first direction.
