BASED ON TDLAS TECHNOLOGYBASED ON TDLAS TECHNOLOGY Tunable Diode Laser Absorption Spectroscopy (TDLAS)
- Every gas absorbs specific wavelengths (frequencies) of light
- The RMLD laser beam emits a specific wavelength which is absorbed by methane
- The amount of laser light absorbed is proportional to the total amount of gas in the path of the laser beam
- Concentration is then expressed as parts-per-million-metered, or “ppm-m”. Concentration times plume width.
TECHNICAL APPROACHTECHNICAL APPROACH Laser light beam is remotely projected on to a target (e.g., grass, wall,
etc.) A fraction of the beam is scattered from the target surface and returned
to the source Returned light is collected and focused onto a detector The presence of methane is encoded within the returned light Methane readings are displayed in ppm-m
