A calibration-free first harmonic (1t ) wavelength modulation spectroscopy (1tWMS) technique for gas species parameter measurement is demonstrated. In this technique, the total magnitude of the 1t-WMS signal is normalized by a component of the 1t residual amplitude modulation signal. This method pre...
