WHITE PAPER LEICA ABSOLUTE INTERFEROMETER A New Approach to Laser Tracker Absolute Distance Meters

the major laser tracker manufacturers had brought some form of In the ideal world, a laser tracker would combine the ability to ADM technology to market, but Leica Geosystems always remained instantly re-establish a broken laser beam and immediately start the accuracy leader. Some of our competitors didn’t view accuracy measuring a moving target. At the same time, it would measure as a key priority, to them speed was more important. The problem absolute distances with the highest precision and would be with these “fast” ADM systems was that using the ADM considerably arbitrarily fast with near...

these parameters is like using a better previously, but uses the information from the IFM to compensate for scale to measure with; the higher the the moving wave form. As soon as the minimum point is calculated, modulation frequency and the smaller the absolute distance is fed back to the IFM, changing it from a the synthesizer re­olution, the more s relative interferometer into an interferometer with an absolute accurate the achievable result is. The reference, or what we refer to as an “Absolute Interferometer”. new design in the AIFM has further increased the maximum modulation The measurement...
