Technical Training Seminar: Laser Trackers: the Local Positioning Technology (LPT)

Laser trackers are used at CERN for different applications within the LHC Project. Leica Geosystems AG have been developing during the last four years the revolutionary Local Positioning Technology (LPT).

Laser trackers are increasingly used to ensure accuracy of large fabrications, and alignment in the final assembly process. Competing portable Coordinate Measuring Machines (CMM) with articulated arms require a frequent repositioning, known to lead to a loss of accuracy and efficiency. Leica Geosystems developed armless solutions, the T-Probe and T-Scan, for use with its laser trackers. The combination of the tracker technology with photogrammetry is the base of LPT, enabling real time measurements with free hand-held devices, such as the T-Probe and T-Scan.

T-Probe and T-Scan overcome the problems that plagued the laser tracker industry, the need for a direct line of sight to perform measurements. The T-Probe is made of a carbon fibre composite, insensitive to temperature changes and shock-resistant. Completely wireless, ultra-light, the T-Probe can be used for easy and flexible measurements of any geometry in large volumes. Using its remote trigger, measurements can be taken within areas of up to 30 meters. The T-Scan captures 10,000 points per second, offering the benefit of digitizing large objects quickly. It is insensitive to different surfaces and needs no surface preparation.

Leica Geosystems also focus on software innovations aimed at running standard Coordinate Measuring Machines and CAD software with laser trackers. The new emScon open software interface enables the embedding laser trackers in any application software: with this web solution measurements are possible via the web.
