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, the TopMap series of optical profiler systems are the preferred solution. From microscopes to macroscopes, Polytec has a product to meet the toughest of applications needs.
Visit Polytec around the world at trade fairs and conferences, or sign up to one of our online seminars, user meetings or customer seminars to find out more about the principles, advantages and various uses of optical measuring technologies!
