Interferometric Displacement Measurement

quDIS Interferometric Distance Measurement - three channels in the 19" rack.
General distance and vibration measurement - the laser beam is adjusted by an sensor head and reflected by a mirror or retroreflector.

The quDIS is a confocal displacement sensor, by default based on a Fabry-Pérot interferometer, with highest signal stability of < 0,05 nm and a contrast independent measuring algorithm.

Next to displacement and distance measurement, vibration analysis is possible with a 25 kHz bandwidth in free space or glass rods & fibers as cavities.

Sensor Heads

All applications require different constrains for collimation, focusing and the beam profile, depending on their reflecting targets. The shaping of the laser beam is achieved by different sensor heads. All these sensor heads for quDIS are based on optical fibers, well-established in the telecommunication market.

Next to standard collimators and established focusing heads, qutools designs special heads for applications in harsh environments.

The design of a sensor head for measuring objects at high temperature drifts.

This collimator is manufactured of a nickel–iron alloy with low coefficient of thermal expansion.
