Understanding Laser Tracker Targets

Abstract

Ninety-seven slides on the thing most tracker users think least about. Ken Steffey starts from the word itself – cooperation being the process of working or acting together, which can be accomplished by intentional and non-intentional agents – to define a cooperative target as a reflector that returns the beam within the range of parameters the tracker expects. From there the talk works through what happens as the target moves in zenith and azimuth, what the incident ray does inside the reflector, and what all of it means for the measurement you get back.
