Temporal Resolution of Acoustic Process Emissions for Monitoring Joint Gap Formation in Laser Beam Butt Welding

open access: yesApplied Sciences, 2023
With the increasing power and speed of laser welding, in-process monitoring has become even more crucial to ensure process stability and weld quality. Due to its low cost and installation flexibility, acoustic process monitoring is a promising method and

Dispersion monitoring for high-speed WDM networks via two-photon absorption in a semiconductor microcavity [PDF]

open access: yes, 2006
Due to the continued demand for bandwidth, network operators have to increase the data rates at which individual wavelengths operate at. As these data rates will exceed 100 Gbit/s in the next 5-10 years, it will be crucial to be able to monitor and ...

Monitoring polymeric compounding processes inline with THz time-domain spectroscopy

open access: yesPolymer Testing, 2009
Abstract We demonstrated the potential of terahertz spectroscopy for contactless and nondestructive inline control of polymeric compounding processes. Using a fiber-coupled terahertz spectrometer, we investigated molten polymers and polymeric compounds.

Heat as a proxy to image dynamic processes with 4D electrical resistivity tomography [PDF]

open access: yes, 2019
Since salt cannot always be used as a geophysical tracer (because it may pollute the aquifer with the mass that is necessary to induce a geophysical contrast), and since in many contaminated aquifer salts (e.g., chloride) already constitute the main ...
