This study presents a tunable multi-gas spectroscopic scheme using a dual-comb architecture operating within the near-infrared domain. The dual-comb signal is generated by two gain-switched ...

Gas in scattering media absorption spectroscopy (GASMAS) is a novel optical technology employing near-infrared light. It has a potential use in the medical setting as a monitoring and diagnostic tool ...

Farming, energy production, and landfills produce methane, a potent greenhouse gas. Forests can remove methane from the atmosphere through the activity of soil bacteria. But increasing precipitation—a ...

The quest for the reliable direct detection of hydrocarbons from seismic data is probably as old as seismic data processing and interpretation itself. Over the years a few different methods have been ...

In most cases, the velocity of sound in partially saturated rock is significantly greater than in pure gas under the same pressure and temperature. What this means is that the wave-propagation process ...
