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.

(canceled)
An optical position acquisition member comprising:
- a base plate comprising an opening configured to receive a CMM measuring probe;
- a light source mounted on the plate and comprising a central axis;
- and
- an optical sensor mounted on the plate,
- wherein the central axis of the light source is within 100 millimeters of a center of the opening.
An articulated arm CMM comprising a plurality of articulated arm members, a base at a proximal end, an optical position acquisition member mounted at a distal end, and a last axis of rotation at the distal end, the acquisition member comprising:
- a light source comprising a central axis parallel to the last axis and within 100 millimeters of the last axis;
- and
- an optical sensor positioned to image an object illuminated by the light source to allow measurement of a plurality of coordinates on the object using the image.
An articulated arm CMM comprising a plurality of articulated arm members, a base at a proximal end, an optical position acquisition member mounted at a distal end, and a handle mounted at the distal end, the acquisition member comprising a light source and an optical sensor positioned to image an object illuminated by the light source to allow measurement of a plurality of coordinates on the object using the image,
- wherein a maximum vertical height of the articulated arm CMM along the last axis is no greater than 260 millimeters.
An articulated arm CMM comprising a plurality of articulated arm members, a base at a proximal end, an optical position acquisition member mounted at a distal end, and a handle mounted at the distal end, the acquisition member comprising a light source and an optical sensor positioned to image an object illuminated by the light source to allow measurement of a plurality of coordinates on the object using the image,
- wherein the acquisition member is centered about a last axis of the articulated arm CMM.
