The Optomet SWIR Scanning Vibrometer is a scanning laser Doppler vibrometer that measures surface vibration without contact. Using the Doppler principle, it directs a laser beam at a target and derives velocity, displacement and acceleration from the frequency shift of the reflected light. The scanning head steps the beam across a defined grid of points, recording the vibration at each one to build a full-field map of how the object moves.
The measurement laser operates at 1550 nm in the short-wave infrared (SWIR) band. Combined with a large optical aperture, this wavelength allows measurements on surfaces with low or varying reflectivity and on complex geometries without applying reflective film or other surface preparation. Signal processing is digital and based on Optomet’s UltraDSP technology, with displacement resolution below 100 femtometers, a frequency bandwidth from DC to 25 MHz and velocities up to ±30 m/s.
Measurement range is set by interchangeable decoders, from the Basis decoder (5 m/s, 100 kHz) to Master++ (30 m/s, 25 MHz), with optional displacement and acceleration decoders. Decoders can be retrofitted without returning the instrument to the factory. The system measures at working distances up to 100 m, and a close-up unit extends measurements down to a few millimetres. A Full HD camera with 30x optical zoom and a visible target laser support targeting.
The instrument can run in scanning mode with OptoSCAN software or single-point mode with OptoGUI, both over Gigabit Ethernet. It is used for vibration and geometry analysis, modal parameter determination, defect resonance detection in composites, rotating machinery analysis and acoustic and ultrasonic measurements across fields such as automotive, aerospace, materials research, civil engineering and medical technology.
