Abstract

An optical displacement transducer using pulsed laser light and a triangulation principle has been developed to measure the lateral vibration of Advanced Gas-cooled Reactor (AGR) fuel stringer tie bars in a laboratory pressurised flow rig. Three pairs of orthogonally mounted units provide positional data to a resolution of < lOμm in the frequency range 0-600Hz.
