There are several sources of error in a laser scanner measurement. The optical and material properties of the target, the shape, form, surface texture, color, reflectivity, and orientation of the target in space, environmental effects, etc., all contribute

Assessing Ranging Errors as a Function of Azimuth in Laser Trackers and Tracers

April 18, 2013

Author(s)

Balasubramanian Muralikrishnan, Vincent D. Lee, Christopher J. Blackburn, Daniel S. Sawyer, Steven D. Phillips, Wei Ren, Ben Hughes

Tilt and radial error motion of a laser tracker head as it spins about the two axes results in small but measurable ranging and angle errors. The laser tracer, on the other hand, measures range with respect to the center of a high quality stationary sphere
