Laser rotational vibrometers and their application in modal analysis
conference contribution
posted on 2015-12-03, 14:34 authored by Steve RothbergMany vibration engineers are now familiar with single
beam Laser Vibrometers which are suitable for
translational vibration measurements but fewer are
familiar with Laser Vibrometers with a pair of parallel
probe beams which are used for rotational vibration
measurements. This paper explains why the parallel
beam configuration is so effective, comparing this with
early uses of cross-beam arrangements and concluding
with an application of these so-called ‘Rotational
Vibrometers’ in the evaluation of a torsional absorber
using modal analysis.
