ICI’s Tunable Diode Laser Absorption Spectrometer (TDLAS) is an innovative long-range detector which allows methane gas (CH4) to be detected at distances of up to 50 m in as little volume as 1 pmm.m. Detects methane by emitting infrared light and examining reflected light density. It can be fixed mounted or attached to an aerial vehicle.
The review also includes commercially unavailable technology such as the electronic nose and the Tunable Diode Laser (TDL) IR Spectrometer. It was found that the TDL could meet the majority of these criteria including fast response, minimum maintenance, portability, and reasonable cost.
A deconvolution procedure commonly used for resolution enhancement of spectra has been applied to the determination of the response function of a tunable diode laser spectrometer. The method is sufficiently fast and simple for routine application when correcting for nonnegligible instrumental broadening.
A fast tunable diode laser spectrometer was applied for measurements of N 2 O emissions from a harvested wheat field located in Sealand, Denmark. The dual-channel instrument uses two tone frequency modulation and signal detection at 11 MHz in conjunction with rapid (1 ms) scanning of the laser. A dichroic beam combiner and a mechanical chopper allow time multiplexing. The absorption signals ...
