In this paper we have demonstrated a unique Tunable Diode Lidar gas imaging technology that meets these requirements. It utilises mature, robust, and highly cost effective and scalable nearinfrared telecommunications components in a unique configuration for spectroscopic Lidar. The technology provides highly accurate CH4 concentration imaging using an active scanning technique that can cover ranges of hundreds of meters. We have presented results of field trials of this technology carried out with the help and support of the National Physical Laboratory. This has demonstrated the capability of the technology for imaging CH4 emissions nominally as low as 0.012 g/s and larger leaks at ranges of up to 90 m. We have also previewed some results of trials at TOTAL’s TADI platform where we demonstrated the sensor operating in a realistic industrial facility
