vibration

An accelerometer can measure some aspects of vibration. However, this entry deals primarily with mechanical devices (often described as vibration switches) and piezoelectric devices (often described as vibration sensors) that are solely intended to measure vibration.

A vibrometer measures vibration using a laser beam aimed at a reflective spot applied to a surface. It is usually a laboratory instrument, beyond the scope of this Encyclopedia.
