Basic principles of laser Doppler vibrometry
Laser vibrometry or more specific laser Doppler vibrometry is a precision optical measurement technology used for determining vibrational velocity and displacement at a fixed point. The laser Doppler vibrometry is a non-contact technology with unrivalled precision based on the Doppler-effect, using the frequency shift of back scattered light from a moving object surface.
