Optical Methods for Vibration Measurements in Nuclear Applications
| 2020:659 | Kalle Raunio, Vesa Nieminen and Juha Virtanen
Optical vibration measurement systems have proven to be capable to measure vibrations in large objects in an industrial environment, and they are developed continuously to be more robust for harsh environment monitoring.
This survey presents a wide range of different methods for capturing vibration behavior and target characteristics, assessed from the preconditions of measuring vibrations in a nuclear power plant.
Depending on what needs to be measured and the preconditions at the site of the vibrating component, usually only certain methods are applicable. Thereby an understanding of measurement method principles, of features and suitability, and of course also of measurement costs is required.
