TDLAS Gas Detection Principles

Most laser gas detection monitors are based on tuneable diode laser absorption spectroscopy (TDLAS). The identification of gas species by absorption spectroscopy goes back several decades. A molecule can be identified by its characteristic absorption spectra. If the frequency (or wavelength) of the infrared (IR) light source matches the vibrational frequency of the molecule, then light will be absorbed. The Beer- Lambert law is the linear relationship we use to calculate molecule concentration (ppm) from the characteristic absorption a molecule exhibits.

One of these absorption features is chosen that does not coincide with any other molecule absorption spectra. The wavelength of the tuneable laser is set very close to the absorption feature we want to measure. A laser is ideally suited for this - as the light output is monochromatic. The laser wavelength is then scanned back and forth over this absorption feature. The resulting change in laser intensity when scanned over the absorption feature provides the information required to calculate the molecule concentration.
