    Introduction OPTICAL HEAD LASER DETECTOR OUTLET WINDOW PRESSURE SENSOR INLET FAR MIRROR 0.8 m Measurement Cell Figure 1–1 Schematic of typical tunable diode laser absorption spectrometer Due to their inherent structure, the molecules in the sample gas each have characteristic natural frequencies (or resonances). When the output of the laser is tuned to one of those natural frequencies, the molecules with that particular resonance will absorb energy from the incident beam.

    SS500/SS2000 Analyzer of raw data results from ramping the current to tune the laser, which not only increases the wavelength with current, but also causes the corresponding output power to increase. By normalizing the signal by the incident intensity, any laser output fluctuations are canceled, and a typical, yet more pronounced, absorption profile results.

  • Page 17: Wavelength Modulation Spectroscopy (Wms) Signal Detection

    Introduction Note that contamination of the mirrors results solely in lower overall signal. However, by tuning the laser off-resonance as well as on-resonance and normalizing the data, the technique self calibrates every scan resulting in measurements that are unaffected by mirror contamination. Wavelength Modulation Spectroscopy (WMS) Signal Detection SpectraSensors takes the fundamental absorption spectroscopy concept a step further by using a sophisticated signal detection technique called wavelength...
