Basic principles of laser Doppler vibrometry
Laser vibrometry is a high precision optical measurement method for the non-invasice determination of vibrational velocity and amplitude of a sample surface. Based on the Doppler effect it evaluates the frequency shift of backscattered laser light from a moving object surface. Learn more about the measurement principle and interferometer setup in this new video.
