Laser vibrometers, also known as Laser Doppler Vibrometer, are non-contact devices used for measuring vibration velocity and displacement on a target surface. These instruments utilize the Doppler effect to determine the frequency shift of laser light reflected off a vibrating surface. By analyzing the frequency shift, laser vibrometers can accurately measure the vibration characteris... https://ommatidia-lidar.com/laser-radar-beyond-doppler-vibrometry-fmcw-lidar-1690
