Many industries, including the automotive and aerospace industries, must precisely measure the threedimensional features of large objects. An increasingly popular way to do this is with the laser tracker, a device first introduced in the late 1980s.
Abstract::
Some laser trackers can measure object features up close and as far away as 60 meters. Some have typical single-point accuracy of about 0.001" (25 micrometers) at distances to several meters. Trackers collect coordinate data at high speed and require just one operator. They offer improved methods of coordinate measurement and make entirely new manufacturing methods possible.
