1 Digital SWIR Scanning Laser Doppler Vibrometer Scan-Series OptoMET Scanning SWIR Laser Doppler Vibrometer (SLDV) is used for non-contact measurement, visualization and analysis of structural vibrations. It determines the Operational Deflection Shapes and Eigenmodes as easily as taking a video. Entire surfaces can be scanned automatically using flexible measurement grids. This powerful scanning system offers state-of-the-art digital signal processing Technology with extensive software for data acquisition, 3-D visualization and analysis. non-contact and non-reactive This system is non-contact, so there is no need to attach sensors or run cables. Measurements can be made from close up to large working distances. Very compact and easy to operate The scanning system is very compact with a modern All-in-One design. Only a single USB connection to a PC or Laptop is needed to start a measurement. Latest Scanning Technology You get a build-in full HD 30 x zoom camera for Pin sharp video. Large Objects can be captured with a large aperture and low-noise scanner providing a 50 x 40 scan area. High-Speed measurements You can measure velocities up to 24.5 m/s. Excellent signal level With its new stabilized SWIR laser you get a very good signal-to-noise ratio on all technical and organic surfaces. The vibrometer is laser safety Class 2 - safe operation without laser safety restrictions. Highest accuracy and resolution Due to our ultra fast Digital Signal Processing the vibrometer achieves highest accuracy in combination with an outstanding resolution down to 1.7 nm/s for velocity and 50 fm for displacement. Large working distance Thanks to its powerful SWIR laser measurements can be made accurately from large working distance, for example to measure a bridge, an airplane or a ship etc..
