By utilizing an active vision system built into the sensor the Leica Absolute Tracker AT901 can determine where a target is without the need for the laser beam to be locked on and without operator intervention. This revolutionary vision system works with all standard reflectors and all Leica T-Products and can lock on to the target as soon as it is within view of the sensor.
Absolute Interferometer (AIFM)
In the ideal world, a laser tracker would combine the ability to instantly re-establish a broken laser beam and immediately start measuring a moving target. At the same time, it would measure absolute distances with the highest precision and would be arbitrarily fast with near zero integration times (the time required to determine the target’s position). Until now no single distancing unit was capable of this, so laser tracker manufacturers were forced to use both laser interferometers (IFM) and Absolute Distance Meters (ADM) separately.
The AIFM combines the best of both worlds and measures absolute distances to a moving target without a loss in accuracy. It represents Leica Geosystems’ most accurate and stable dynamic distancing unit.
6 Degrees of Freedom
The Leica T-Cam, part of every Leica Geosystems Portable Coordinate Measurement System (PCMM) or as an add-on option for existing Leica Geosystems Laser Trackers migrating from reflector measurements to other target devices, is a CMOS digital camera system operating with visible light and near infrared (IR) radiation, with an optical vario zoom and a motor for vertical, angular movement.
A reflector integrated in a target device, together with a set of LEDs embedded on the surface of the target device, represent the measurement targets of the system. Six measurement parameters describe the target device in relation to the laser tracking system completely. These are 3 position parameters (x, y and z) and 3 orientation parameters (pitch, yaw and roll). Together, they comprise the Six Degrees of Freedom (6DOF) principle. These parameters are determined by the Leica Absolute Tracker AT901 (position) and the Leica T-Cam (orientation).
