Leaking methane (CH4) from infrastructures, like pipelines, industrial complexes and landfills, or accidental hazardous goods transports is critical for the environment, but can also pose a risk to human life. To enable a fast detection and localisation of these kind of leaks, we developed a novel robotic platform for aerial remote gas sensing. The platform combines an unmanned micro aircraft (UAV), a 3-axis aerial stabilisation gimbal and an open-path gas detector based on the tunable diode laser absorption spectroscopy (TDLAS).
An unmanned micro aircraft (UAV) is equipped with an open-path gas detector to localise gas sources and to generate gas distribution maps. The gas detector is based on the tunable diode laser absorption spectroscopy (TDLAS) and attached to a 3-axis aerial stabilisation gimbal. Sensor validation experiments and first gas tomography reconstructions are shown.
