摘要：

We present a signal-processing system developed for absorption-based gas sensing based on wavelength modulation of a laser diode. The system provides an accurate method for the measurement of gas concentration. An implementation is described which utilizes analog components for the realization of an industrial high resolution calibration set-up for methane sensors, with an InGaAsP laser diode at 1.331 mu m.
