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.
For measuring the finest details in surfaces by areally characterizing form parameters without contact, the TopMap optical profilers are the preferred solution. From microscope to macroscope quality control applications, Polytec offers turnkey surface metrology solutions for industry and research.
