vibrometer
Shaking detection device
A vibrometer is an instrument that measures vibration—typically the displacement, velocity, or acceleration of a vibrating surface.
Laser vibrometers use reflected light to measure without physical contact, making them useful for delicate or rotating machinery.
Engineers use vibrometers to diagnose mechanical problems, test structural integrity, and analyze acoustic properties: The vibrometer detected excessive vibration in the turbine blade.
