Method & Evidence

AimTo develop and deploy a differential absorption lidar (DIAL) system capable of identifying carbon dioxide leakage from sequestration sites.

MethodDevelopment and deployment of a custom-built lidar system, followed by field testing and comparison with in-situ sensors.

ProcedureA near-infrared scanning micropulse DIAL transmitter was constructed using tunable diode lasers, an acousto-optic modulator, fiber optic switches, and an Erbium-doped fiber amplifier. A Schmidt-Cassegrain telescope collected backscattered light, which was optically filtered and detected by a fiber-coupled photomultiplier tube. The system was programmed to scan over a field area using a motorized telescope base. Autonomous field measurements were conducted and compared with an in-situ sensor.
