Vector-Micro-Optics - Optomet

Product Description

The Optomet Vector-Micro-Optics is an optical measurement head that extends the Vector laser Doppler vibrometer series for vibration measurements on very small objects. It pairs micro-optics that focus the measurement laser to a spot of about 3.7 µm with a 12 MP 4K camera used to place that spot precisely on the test object. It is used in electronics development and for measurements on electronic components and other structures too small for a standard vibrometer spot.

The head uses the Vector series’ visible HeNe laser at 632.8 nm. Vibration is measured by the Doppler principle: light reflected from the vibrating surface is shifted in frequency, and the decoder electronics convert this shift into velocity, with displacement and acceleration available through optional decoders. Because the measurement is optical, no sensor is mounted on the surface and no mass is added to the object.

The laser spot is approximately 3.7 µm in diameter at a working distance of about 21.5 mm, with a depth of field of 0.022 mm. The integrated camera (4000 × 3000 pixels, USB 3.1) gives a magnified view for aiming, and a built-in contrast adjustment filter helps make the laser spot visible on the target. The available frequency and velocity ranges are set by the selected Vector decoder series, spanning from DC–100 kHz at 2 m/s up to DC–25 MHz at 10 m/s; with Optomet’s UltraDSP technology, displacements can be resolved to less than 100 fm. Decoder modules can be retrofitted without returning the unit to the factory. The system is operated through the OptoGUI software over Gigabit Ethernet for single-point data acquisition and analysis.
