Laser Trackers for Large Scale Dimensional Metrology: A Review

Abstract

Thirty years since their invention, laser trackers are now recognized as the measurement tool of choice in the manufacture and assembly of large components. While their general design, i.e., a ranging unit on a two-axis gimbal, has not changed significantly over the years, interferometers (IFMs) are now giving way to increasingly more accurate absolute distance meters (ADMs). Hand-held accessories such as touch probes and line scanners are expanding the scope and applicability of laser trackers. We survey reported literature in all areas of laser trackers as applied to large scale dimensional metrology (LSDM), with emphasis on error modeling, measurement uncertainty, performance evaluation and standardization.
