Linking distributed and integrated fiber-optic sensing
Daniel C. Bowden, Andreas Fichtner, Thomas Nikas +7
Distributed Acoustic Sensing (DAS) has become a popular method of observing seismic wavefields: backscattered pulses of light reveal strains or strain-rates at any location along a…
Sensitivity kernels for transmission fiber optics
Andreas Fichtner, Adonis Bogris, Daniel Bowden +6
Fiber-optic sensing technologies based on transmission offer an alternative to scattering-based Distributed Acoustic Sensing (DAS). Being able to interrogate fibers that are thousa…
Introduction to phase transmission fibre-optic sensing of seismic waves
Andreas Fichtner, Adonis Bogris, Thomas Nikas +6
This manuscript is concerned with phase changes of signals transmitted through deforming optical fibres. As a first result, it establishes an exact relation between observable phas…
Diffuse ultrasound computed tomography for medical imaging
Ines Elisa Ulrich, Christian Boehm, Andrea Zunino +2
An alternative approach to ultrasound computed tomography (USCT) for medical imaging is proposed, with the intent to (i) shorten acquisition time for devices with a large number of…
