Dissolved gas monitoring probe without liquid-gas separation under strong electromagnetic interference [PDF]
arXiv, 2022 Rapid and direct monitoring of dissolved gases in liquids under strong electromagnetic interference is very important. Electronic gas sensors that can be placed into liquids are difficult to work reliably under strong electromagnetic fields. The existing optical monitoring techniques for dissolved gases all require gas-liquid separation, and are ...

Turbulence monitoring at Calern observatory with the Generalised Differential Image Motion Monitor [PDF]
, 2020 The Generalised Differential Image Motion Monitor (GDIMM) was proposed a few years ago as a new generation instrument for turbulence monitoring. It measures integrated parameters of the optical turbulence, i.e the seeing, isoplanatic angle, scintillation index, coherence time and wavefront coherence outer scale.
