Laser radar-based measuring systems for large scale assembly applications

Long term research on pulsed time-of-flight laser distance measurement has opened new dimensions in measurement applications, from large scale assembly in shipbuilding to precast concrete element production, leading to improved quality control and more efficient manufacturing. The ACMAN 3-D coordinate meters measure the coordinate values of a point in terms of radial distance and two angles directly from natural surfaces. The accuracy of coordinate values is 1 mm (1-sigma) in the measurement range of 3 - 30 m. The functions of the automatic ACMAN 200 include pointing with a red beam, automatic searching and measuring of marked target points and shape measurement by scanning. Coaxial optics of measuring, pointing and aiming provide the optimal measurement geometry. ACMAN 3-D coordinate meters are integrated into the ACMAN 1000 and ACMAN 2000 series dimension control systems.
