High‐speed cameras and laser Doppler vibrometers

Abstract

PurposeTo present two non‐contact methods of measuring vibrations and impact events.Design/methodology/approachThe paper concentrates on the practical capabilities and underlying technology of commercial high‐speed CMOS cameras and laser Doppler vibrometers.FindingsThe instruments are used to analyse modes of failure and to test quality in a very wide range of products. They are also used to develop safety and protective devices, and to study natural phenomena.Originality/valueA practical guide to the tools available, with some example applications of interest to production engineers.
