Scanning laser Doppler vibrometer
Optomet

Scanning laser Doppler vibrometry is a full-field vibration imaging measurement technique in which the vibrometer measurement beam scans the test object and records the vibration data of a grid of measurement points within a short time. The Optomet scanning laser Doppler vibrometer (SLDV) combines the superior signal quality of infrared laser vibrometry with beam deflection mirrors, an HD video camera, an integrated signal generator and inputs for reference channels, resulting in one of the most modern, innovative laser vibrometry systems worldwide.

With Optomet’s OptoSCAN software, the scanning laser vibrometer becomes a turnkey, intuitively operated vibration visualization system. The non-contact vibration measurement of any test structure provides precise, valuable insight into the dynamic behavior of the structure. Operating and structural vibrations can be animated, resonances identified, finite element model calculations validated and the energy propagation of surface waves made visible.

Optomet pioneered the world’s first short-wave infrared (SWIR) laser-based scanning laser Doppler vibrometer, which eliminates the need for surface treatment and produces the highest-quality data through superior measurement sensitivity.

The Optomet scanning laser Doppler vibrometer has the industry’s largest optical aperture, maximizing the collection of reflected laser light. This ensures the highest-possible measurement sensitivity even at points with minimal laser backscattering. High-quality materials and attention to detail result in extreme reliability and durability. Benefit from measuring vibrational velocities up to ±25m/s and a frequency bandwidth from DC up to 24Mhz. Resolutions down to 50 femtometers qualify the scanning vibrometry system for any measurement task, from large buildings to microstructures.
