Tdlas 원리

WebA standard TDLAS setup consists of: a wavelength tuning DFB laser; emitting monochromatic light at the absorption line of the trace gas. an optical lens to collimate the laser light. a gas sample cell; in this case filled with H 2 O. a photo detector on which the laser light is focused; measuring the transmission. WebTDLAS technology. SUMMARY TDLAS is a sensitive tool for measuring low levels of moisture in the presence of interfering species, such as methane in natural gas. The signal-to-noise ratio is superior because the detection is carried out at frequencies far from the baseband noise. TDLAS is a dependable technique, especially with laser line lock.
