title = "Drone-assisted multi-trace-gas sensing with mid-infrared quantum cascade laser frequency combs",
abstract = "We present a mobile drone-assisted dual comb remote sensor based on mid-infrared quantum cascade laser frequency combs for simultaneous sensing of multiple atmospheric trace gases. The remote sensor is equipped with an active drone tracking hardware that allows for continuous tracking of a retroreflector mounted on a lightweight drone. As a proof-of-concept demonstration, we conduct a laboratory measurement test with R-134a (Freon), a refrigerant with large global warming potential. Intermittent releases of the chemical are reliably detected over 4 minutes of continuous drone flying and tracking, thus showing excellent gas sensing and drone tracking capability. This work shows great potentials for realizing compact and portable remote sensors for chemical emission localizations.",
