Paper Abstract

Previous studies have demonstrated convenient techniques using a continuously-scanning Laser Doppler Vibrometer for measuring and quantifying vibration mode shapes defined along straight or circular scan lines, and for measuring angular vibration. This paper concentrates on a new conical- scanning technique which gives an easily-quantifiable measure of the magnitude and direction of the vibration of a point, even if the vibration is in-plane. Where the vibration is complex (i.e. it follows an elliptical path), derivation of the component vectors is more difficult. However, easy solutions exist for some practical special cases.
