Leica AT 901 MR Laser Tracker system

LEICA AT 901

Leica AT 901 MR Laser Tracker system In the ideal world, a laser tracker would combine the ability to instantly re-establish a broken laser beam and immediately start tracking a target. At the same time, it would measure absolute distances with the highest precision and would be arbitrarily fast. Keeping the integration time (the time required to perform the mathematical operations to determine the target’s position) down to a minimum is paramount when tracking moving targets. Historically, most laser trackers have used either absolute distance meters (ADM) or interferometers (IFM) to get the job done.

The AT901 can gather 3D coordinates in 3 ways: by following a small mirrored sphere, also known as a reflector; by tracking a Leica T-Probe, a hand-held “walk-around” wireless contact probe; or by tracking a Leica T-Scan, a contactless high-speed laser scanner. Which measurement method you should use will depend on your application. This is the laser tracker that set the new benchmark for aerospace and other large scale precision measurements such as windmill blade inspection or industrial machinery alignment. The Leica AT901 can be used in numerous industries including: Aerospace, Automotive, Power Generation, Defence etc.

PowerLock

PowerLock vision technology completely changes the way that laser trackers have been used. No longer do operators have to worry about the laser beam, they can simply measure what is needed and let the tracker lock on to them!

Leica Absolute Interferometer (AIFM)

The AIFM is a single distancing unit with the dynamic performance of an interferometer, and it has the ability to re-acquire a moving target with the typical uncertainty of lock-on process being less than 5 μm.

Six Degrees of Freedom

By adding photogrammetric capabilities to the laser tracker, Leica Geosystems created the world’s only technologically mature PCMM system that can probe like a fixed CMM, scan like a laser scanner and track automated applications – all in one system.

High speed dynamic measurement

Thanks to the AIFM, PowerLock and its capability to deliver real-time measurement data, the Leica Absolute Tracker AT 901 is a captivating piece of technology enabling high intensity measurement applications, e.g. automated systems.
