Scanning Vibrometer

| Component | Function | |-----------|----------| | Laser source (He-Ne or infrared) | Illuminates target | | Interferometer (e.g., Mach-Zehnder) | Detects Doppler shift | | Scanning mirrors | Direct beam to X/Y positions | | Controller & software | Coordinates scan, processes data | | Video camera (optional) | Overlays vibration data on live image |

Instead of looking at a graph of vibration at a single spot, engineers get a "heat map" or animation of the entire structure. You can see the —literally watching how a car door flexes or how a circuit board bends when dropped. scanning vibrometer

Car manufacturers use scanning vibrometers to locate "buzz, squeak, and rattle" issues. By scanning a dashboard or a door panel while the car is on a test track, engineers can pinpoint exactly which plastic clip is loose or which panel is resonating, leading to quieter luxury vehicles. | Component | Function | |-----------|----------| | Laser
