Device for determining the perimeter of the surface of an object being scanned and for limiting reflection from the object surface
First Claim
1. An apparatus for determining the perimeter of an object being scanned, comprising:
- a) a plate for orbiting around the object being scanned;
b) a movable arm (operably) secured to said plate, said arm for following the surface of the object being scanned as said plate is orbited around the object;
c) said arm having one end for maintaining contact with the surface as said plate is orbited around the object; and
d) an encoder connected to said arm for determining the movement of said arm as said plate is orbited around the object.

Abstract
An apparatus for determining the perimeter of an object being scanned comprises a movable arm adapted to follow the surface of an object being scanned as the arm is orbited around the object; the arm having one end being adapted to maintain contact with the surface as the arm is orbited around the object; and an encoder operably connected to the arm for determining the movement of the lever arm at each angular position around the object. An opaque cup is positioned at one end of the lever arm immediately over a point on said surface at which a laser beam impinges on the surface of the object being scanned such that reflection from the surface is retained within the cup.

9. An apparatus for bringing a source of laser beam to the surface of an object being scanned, comprising:
-
a) a plate for orbiting around the object being scanned; b) a movable support secured to said plate; c) a fiber optic cable supported by said movable support, said fiber optic cable for being connected to a source of laser beam; d) a lens coupled to one end of said fiber optic cable, said lens for being in intimate contact with the surface of the object being scanned as said plate is orbited around the object; and e) said movable support including a spring for permitting said lens to follow the perimeter of the surface of the object being scanned while said plate is orbited around the object. - View Dependent Claims (10, 11, 12, 13)
