Abstract
A hand-held vibrometer for measuring vibration at a surface of a vibrating object includes plural vibration sensors, each of which has a respective axis of measurement. The vibration sensors are mounted on a rigid body so that the respective axes of measurement of the sensors intersect at a contact point on the rigid body, which contact point is to be applied to the vibrating object. The contact point is at a central axis of the rigid body and the respective axes of measurement of the vibration sensors all intersect the central axis of the rigid body at the same angle. Respective amounts of vibration in the vibrating object in three orthogonal measurement axes are calculated on the basis of output signals provided from the plurality of vibration sensors. The above-described arrangement of the vibration sensors increases the contact resonance frequency, and consequently the measurement range, of the vibrometer.
