Principle
TDLAS technology utilizes the principle that laser energy is absorbed selectively by gas to form an absorption spectrum. Laserbeams of specific wavelengths is emitted by semiconductorlaser, and when passes through the gas, the attenuation of the laserintensity is related with measured gas. The concentration can beobtained by measuring intensity attenuation.
