Performance comparison between FOS and PZT AE sensors

Comparison between FOS and PZT AE sensors

The white-paper written in collaboration with CETIM operated by ANDRA is out!  Our optical acoustic emission system OptimAE is ready to tackle difficult measurements in harsh environments, with performance comparable to the state-of-the-art electrical systems.  The fiber-optic sensors were tested in a lab environment and directly compared with the electrical PZT sensors to evaluate sensitivity, directivity, waveforms, signal repeatability and localization accuracy. The fiber-optic system […]
