Thermal Excitation and Piezoresistive Detection of Cantilever In-Plane Resonance Modes for Sensing Applications [PDF]
, 2010 Thermally excited and piezoresistively detected bulk-micromachined cantilevers vibrating in their in-plane flexural resonance mode are presented. By shearing the surrounding fluid rather than exerting normal stress on it, the in-plane mode cantilevers ...

Sediment Corrections for Distributed Acoustic Sensing
Journal of Geophysical Research: Solid EarthOn continental margins, sediments cause significant and spatially variable delays in seismic phase arrival times. The strong impedance contrast of the sediment-bedrock interface causes P-wave splitting that is clearly seen on Distributed Acoustic Sensing recordings of earthquakes, resulting in additional phase arrivals that must be picked separately ...

Acoustic Source Localisation Using Distributed Sensing
Procedia Engineering, 2017 Abstract The actuation of Lamb waves in thin plate-like structures and subsequent interpretation of the scattered wave field offers a capability for broad area damage detection and location. In practice, interpretation of a scattered field can be difficult when there are several overlapping wave modes propagating which is a realistic scenario for ...

Distributed opto-mechanical analysis of liquids outside standard fibers coated with polyimide
, 2019 The analysis of surrounding media has been a long-standing challenge of optical fiber sensors. Measurements are difficult due to the confinement of light to the inner core of standard fibers.

Accelerated High-Resolution Photoacoustic Tomography via Compressed Sensing [PDF]
, 2016 Current 3D photoacoustic tomography (PAT) systems offer either high image quality or high frame rates but are not able to deliver high spatial and temporal resolution simultaneously, which limits their ability to image dynamic processes in living tissue.

Traffic Flow Detection Using Distributed Fiber Optic Acoustic Sensing
IEEE Access, 2018 This paper proposes a novel method for traffic flow detection using distributed optical fiber acoustic sensing (DAS). Different from the traditional traffic flow detection method, this method detects the traffic vibration signal using a fiber optic cable.
