Bridger Photonics products

The oil & gas industry is under tremendous pressure to reduce methane emissions. This pressure has put the industry in an untenable position, as no viable technology has existed to image and quantify this invisible gas in a reliable, sensitive, and cost-effective manner - until now. Bridger Photonics’ Gas Mapping LiDAR™ makes it simple and efficient for the oil & gas industry to reduce methane emissions and improve overall safety. This technology scans oil & gas infrastructures from the air, pinpoints the leaking equipment and quantifies the emission rate. We then create a map that images each plume, eliminating the need to visit each site, so operators only need to deploy field crews when a leak is detected.

FMCW LiDAR uses the frequency (i.e. color) of the laser light to determine distance. This method enables the simultaneous measurement of distance and velocity, generating precise location data.

A continuous-wave laser can be changed or modulated to achieve the same effect as differential absorption. This laser absorption spectroscopy technique is known in various forms as wavelength modulation spectroscopy (WMS), frequency modulation spectroscopy (FMS), or tunable diode laser spectroscopy (TDLAS). Bridger mounts the LiDAR systems on aircraft, so the ground serves as a scattering point of laser light back to the LiDAR system.

Using the fact that each gas absorbs a specific frequency of laser light, pulsed DIAL can determine the concentration of a gas by comparing the returning light from a laser pulse that is absorbed by a gas to a laser pulse that is not absorbed by the gas.
