Immunity to Laser Power Variation in a DFB Diode Laser Based Optical Gas Sensor Using a Division Process
The division process used in a DFB diode laser-based optical gas sensor was studied to improve the immunity to laser power variation. Residual amplitude modulation (RAM) in wavelength modulation spectroscopy (WMS) detection was eliminated by intensity normalization using a division process. As a res...
