BASED 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 tothe 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 plumewidth.

TECHNICAL 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 returnedto 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
