Author(s)
Balasubramanian Muralikrishnan, Christopher J. Blackburn, Daniel S. Sawyer, Bruce R. Borchardt, William T. Estler, Steven D. Phillips
While the versatility and economics of laser trackers are quite appealing, the ability to assess their accuracy and to compare various brands has been limited by a lack of a national or international standard that encompasses testing and traceability

Laser Trackers: Testing and Standards

January 1, 2007
Author(s)
Steven D. Phillips
Laser trackers are now the tool of choice for large scale coordinate metrology. They are transportable allowing reconfigurable production facilities at a lower capital cost than large CMMs. Trackers now include absolute distance measuring (ADM) capability
