Laser vibration measurement systems aka laser Doppler vibrometers rely on the principle of laser interferometry, using an eye-safe laser (e.g. HeNe with λ = 633 nm, P < 1 mW) as light source. Inside the vibration measurement head, an optical beam splitter separates the laser beam into two components: a reference beam and a measuring beam.

A molecular vibration is excited when the molecule absorbs energy, ΔE, corresponding to the vibration's frequency, ν, according to the relation ΔE = hν, where h is Planck's constant. A fundamental vibration is evoked when one such quantum of energy is absorbed by the molecule in its ground state [24].
