Fiber optic sensing with no compromises

Acceleration sensing is a reliable and flexible technique with a wide field of applications, ranging from sub-hertz seismology and structural-health-monitoring (SHM) to high frequency condition monitoring.  Fiber optic sensing provides a solution to measure acceleration in harsh environments where electric transducers struggle to deliver. While overcoming the environmental challenges, classic fiber optic acceleration technologies come with many drawbacks such as limited sensitivity, limited bandwidth, and bulky sensor size which need to be overcome.

DeltaSens delivers the great benefits of fiber optic sensing with none of compromises of classic fiber optic sensing, opening new measurement scenarios in extreme conditions where high performance is required.
