TDLAS Cubic TDLAS Technology Tunable diode laser absorption spectroscopy (TDLAS) is one of the most sensitive and selective technologies used for measuring concentration of gases (methane, O 2 , CO, NH 3 .etc) in a gases mixture by the characteristic of tunable laser source with narrow linewidth and tenability. It is based on Lambert-Beer law which state absorption spectroscopy principles. It consists of tunable laser transmitter, optical measurement path, detector and pressure sensor. Laser source emit laser beam into the gas mixture through optical measurement path, by precisely modulating the current of tunable laser, it can scan a certain absorption peak of detected gas. At the opposite end the detector converts received laser power, attenuated by target gas absorption, into an electrical signal. The detected attenuated electrical signal reﬂects the changes in target gas concentration . Demodulation Phase Sensitive Detection Harmonic spectrum
