  • Excellent bandwidth (up to 10 MHz).

  • Vibration velocity up to 24.5 m/s.

  • Variable working distance of 0 mm to >300 m (with quick-change objective lenses)

  • Compact and extremely powerful (optics and electronics in one housing).

  • Large choice of different decoders for displacement, velocity, and acceleration.

  • Highest optical sensitivity.

  • Easy operation, color touch display, rotary knobs and buttons.

Scanning Laser Doppler Vibrometers

Optomet SWIR Digital Scanning Laser Doppler Vibrometer (SLDV) is used for full-field non-contact measurements, visualization and analysis of structural vibrations. It determines and animates Operational Deflection Shapes and Eigenmodes as easily as taking a video. Entire surfaces can be scanned automatically via user defined measurement points. This powerful scanning system offers ultraDSP, Optomet’s state-of-the-art digital signal processing technology with extensive software for data acquisition, 3-D visualization and analysis.

  • Excellent signal level.

  • Very compact and easy to operate.

  • Highest accuracy and resolution.

  • Latest Scanning Technology.

  • Large working distance.

  • Up to 14 velocity measurement ranges: 2.45 mm/s to 24.5 m/s.

Dual Fiber Digital SWIR Laser Doppler Vibrometers

The Optomet Dual Fiber SWIR Vibrometer consists of a SWIR vibrometer and a flexible Dual-Fiber head.  Various objective lenses either collimated or focused are available.

With its build-in stabilized SWIR laser the Optomet Dual Fiber laser doppler vibrometer gets excellent signal-to-noise ratio on nearly any test surfaces. Thanks to ultraDSP, Optomet’s innovative digital signal processing technology, the vibrometer achieves highest accuracy in combination with an outstanding resolution of 1.7 nm/s for velocity and 0.05 pm for displacement.

With an optional fiber switch, multiple fiber heads can be connected to the vibrometer, which allows users to multiplex multiple channels (2, 4, 8, 16, …).  The fiber switch comes with an electrical interface (Ethernet, USB, TTL, …) and can be remotely operated by a PC.
