QLM has taken a unique approach to the challenge of enabling organisations to effectively monitor emissions of greenhouse gases. Our Tunable Diode Lidar (TDLidar) gas camera offers a quantum approach to quantification.
TDLidar combines the best of two worlds: Drawing on quantum technology, we apply Time Correlated Single Photon Counting (TCSPC) using a quantum Single Photon Avalanche Detector (SPAD). This is combined with aspects of existing open path gas measurement techniques, such as Tunable Diode Laser Absorption Spectroscopy (TDLAS) and Differential Absorption Lidar (DIAL).
TDLidar offers several benefits to the user
- Long-range, high-sensitivity, quantitative imaging of gas plume shape and concentration
- Precise mapping of gas leak locations and quantification of flow rates
- Fixed, mobile, drone and handheld options
- Mains or battery power options
