First Claim
Patent Images
1. An optical position acquisition member comprising:
- a base plate comprising an opening configured to receive a CMM measuring probe;
a laser mounted on the plate; and
an optical sensor mounted on the plate such that the sensor is generally collinear with the laser and the opening, and the opening is between the laser and the sensor.

Abstract
A coordinate measurement device comprises an articulated arm having a first end, a second end, and a plurality of jointed arm segments therebetween. Each arm segment defines at least one axis of rotation. A laser scanner assembly is coupled to the second end of the arm and is rotatable about a last axis of rotation of the articulated arm. The laser scanner assembly comprises a laser and an image sensor. The laser is positioned on an opposite side of the last axis of rotation from the image sensor.

15. A coordinate measurement device comprising:
-
an articulated arm having a first end, a second end, and a plurality of jointed arm segments therebetween, each arm segment defining at least one axis of rotation, a last axis of rotation being defined by bearings near a distal end of the arm; and a laser scanner assembly coupled to the second end of the arm and rotatable about the last axis of rotation of the articulated arm, the laser scanner assembly comprising a laser and an image sensor, the laser positioned on an opposite side of the last axis of rotation from the image sensor, and at least one of the laser and image sensor overlaps the bearings. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)

25. An optical position acquisition member comprising:
-
a base member forming an opening shaped to accept a CMM measuring probe such as a touch probe; a laser mounted on the base member; and an optical sensor associated with the laser such that the optical sensor operatively views light emitted by the laser and reflected from a surface, the optical sensor further being mounted to the base member on a side of the opening opposite the laser. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32)
