FIBER OPTICAL ACCELEROMETER

MEMS SENSOR HEAD for OEM integration


Sercalo's fiber optic accelerometer (FOA) is an opto-mechanical acceleration sensor. The sensing device is a micromechanical Silicon mirror (MEMS) which deflects a light beam proportional to the acceleration. It can be placed in a harsh environment and is separated from the measurement electronics by optical fibers.

The standard measurement direction is along the axial direction. A different variant in the same form factor is available for radial measurement. The sensor head is available in a housing of either stainless steel or ceramic material (MACOR). The steel housing is hermetically sealed and has a laser welded collimator. No epoxy is present in the optical path. This ensures an outstanding long term stability.

The miniature package withstands rugged environments and is intended for integration in customer defined packages. The component is compliant to RoHS requirements 2015/863/EU.
