Laser vibrometers are used to make high-precision displacement, velocity or acceleration measurements when no contact with the structure is required or desired.
The PSV-400 Scanning Vibrometers provide cutting edge measurement technology for the analysis and visualization of structural vibrations. Entire surfaces can be rapidly scanned and automatically probed with flexible and interactively created measurement grids, zero mass loading and no time-consuming transducer mounting, wiring and signal conditioning. The PSV-400 offers technical excellence, ease of use and features, designed for resolving noise and vibration issues in the automotive, aerospace, data storage, micro systems, commercial manufacturing and R&D markets.
