Laser vibrometry is a non-contact measurement technique used to detect and analyze vibrations in various objects and structures. It works by emitting a laser beam onto a target and analyzing the Doppler shift in the laser light reflected off the vibrating surface. This allows for precise measurements of vibration amplitude, frequency, and mode shapes without the need for physical cont... https://ommatidia-lidar.com/laser-radar-beyond-doppler-vibrometry-fmcw-lidar-1690
