Using Microwave Interferometry to Determine the Positional Uncertainty of Dynamic Laser Tracker Measurements at Slow Speeds

Abstract

NIST uses commercial robots to position test antennas and sensors around objects while sampling their electromagnetic emissions, which requires positional knowledge of roughly 20-100 micrometres while the probe is moving. This presentation uses microwave interferometry to determine the positional uncertainty of dynamic laser tracker measurements at slow speeds, examining timing, averaging and triggering behaviour that is not defined for trackers under dynamic operating conditions.
