Uncertainty Contributions Due to Different Measurement Strategies Applied to Optomechanical Hole Plate

摘要

The work described in this paper deals with influence parameters in optical measurements, with particular respect to the choice of measurement strategy, which strongly affects the results of measurement. In this investigation, an optomechanical hole plate developed by DTU was measured with an optical CMM equipped with a CCD camera. Deviations up to 4 μm were observed for centre coordinates obtained using different measurement strategies. These deviations only came from optical influences since no movements of the CMM axes were introduced.
