Abstract
Vibrations of a body are measured by attaching a vibrating element to the body, directing a beam of electromagnetic energy onto the vibrating element and collecting reflected electromagnetic energy from the vibrating element. The magnitude of the reflected electromagnetic energy is processed to determine vibration and/or temperature of the body. The magnitude of the reflected light is preferably a function of second degree of the position of said vibrating element. Processing said magnitude of reflected electromagnetic energy is preferably done by a Fourier series up to a second harmonic.
