OptoMET digital laser Doppler vibrometer is a set of high-precision vibration measurement instruments. The instrument measures vibration and acoustic signals, including vibration displacement, velocity and acceleration, non-contact and accurately. It has ultra-high optical sensitivity and utilizes in-house developed UltraDSP (Ultra Speed Digital Signal Processing) technology to quickly measure vibration not only in simple systems, but also in challenging systems including high frequency vibration, remote testing, small amplitudes, high linearity and high vibration accelerations or velocities. UltraDSP (Ultra Speed Digital Signal Processing) technology ensures high resolution and high accuracy measurements.OptoMET laser vibration meters offer excellent linearity and a wide test bandwidth of up to 10 MHz.
OptoMET laser vibration meters are available in four series: the Vector, Nova, Dual Fiber, and Scan series:
Vector, Nova, Dual Fiber, Scan, and Scan series are available:
Vector, Nova, Dual Fiber, Scan, and Scan series are available.
The Vector series of He-Ne laser vibrometers are general purpose laser vibrometers suitable for most non-contact vibration measurement applications. They are particularly well suited for testing on reflective surfaces or in water, and for applications where the laser spot needs to be as small as possible.
