SMART 3D-Fiber - Optomet

Product Description

The Optomet SMART 3D-Fiber is a 3D single-point laser Doppler vibrometer. It measures vibration at a single point in three orthogonal spatial directions without contact, reporting velocity, displacement and acceleration. The measurement location is reached through a flexible optical fiber and a separate fiber head, so the head can be placed in confined or hard-to-access positions while the main unit stays elsewhere.

The instrument resolves motion in three dimensions by emitting three laser beams from one fiber head at different angles. Each beam is processed by its own interferometer, and the three signals are combined to give the three orthogonal components of the point’s motion. The system handles up to four measurement channels simultaneously and uses a 1550 nm (eye-safe, class 1) measurement laser with a visible target laser for alignment.

The SMART 3D-Fiber covers a frequency bandwidth from DC to 50 MHz and velocities from 1 mm/s up to 50 m/s, with displacement from 10 nm to 100 m and acceleration from 10 m/s² to 100 Mio. m/s². A 7-inch Full HD+ touchscreen and the SMART Lab software handle configuration, phase-correct multi-channel acquisition, real-time FFT and frequency response function analysis, with data export to CSV, H5, MAT and WAV. As part of Optomet’s modular SMART Series, it shares connectivity and form factor with other SMART devices.
