Deltasens research and development readout

The OptimAE is world’s only fiber optic acoustic emission sensing system. Fiber optic sensing systems are by definition highly suitable to measure in extreme environments, like in areas with high voltages, inside ATEX zones, in electro magnetic fields or in liquids.

OptimAE is a modular system that can be configured to a maximum of 16 channels, sampling each channel at 1 MHz. This powerful system will be part of a network, which enables remote accessibility. Using an interferometric measurement principle the sensitivity gets down to femtostrain level while maintaining  a nanometer noise floor. 

The system works seamless with the 6300 AE sensors.

Technology

DeltaSens, based on optical fiber interferometry, offers a completely new way of multiplexing  Fabry Pérot type sensors. Fabry-Pérot sensors are the most sensitive optical transducers with the smallest dimensions. With DeltaSens, a high sensitivity sensing network in a challenging environment becomes reality.

All sensors in the network are sampled simultaneously, such that synchronization-sensitive correlation studies can be performed. The signals of each sensor are based on measuring phase information of the sensor cavity sizes; by tracking this phase over multiple interferometric fringes a large dynamic range is achieved.

Using just a single readout to measure multiple MEMS based Fabry-Pérot sensors makes DeltaSens an affordable solution, without compromising on the sensitivity or bandwidth.
