Laser Speed Sensor - Arcoptix - #1

Self-Mixing Effect using quasi single mode operation of a laser diode allows a robust and compact measurement unit.

Surface insensitive. The

signal quality does not depend on the reflected intensity. The low threshold intensity needed to get a signal allows its use on quasi polished surfaces.

High Precision is achieved by processing the data with a phase discrimination algorithm. Displacement with a sub-micron resolution can be achieved.

High speed data acquisition and

transmission is achieved using a dedicated electronics with the USB 2.0 bus.

ARCsmev (Self-Mixing Effect Velocimeter) patented technology offers new perspectives in the measurement of in-plane displacements. With comparable performances than standard Laser Doppler Velocimeter, the low cost and compactness of the device enlarge the scope of utilization of non-contact displacement measurement.

This unique method use a laser diode driven in a quasi single mode. Mode competition is influenced by the light reflected from the target under measurement. Observing the variation of the emitted mode gives information of displacement. The scheme offers robust signals regarding the surface quality and reflectivity.
