A recursive Kalman time-series filter was applied to absorbance measurements obtained with a tunable diode laser spectrometer. The spectrometer uses frequency modulation spectroscopy and a nearinfrared diode laser operating at 1.604 µm to monitor the CO(2)-vapor concentration in a 30-cm absorption cell. The Kalman filter enhanced the signal-to-noise ratio of the spectrometer by an order of magnitude when an absorbance of 6 × 10(-5) was monitored.
一种递归卡尔曼时间序列滤波器被应用于可调谐二极管激光光谱仪获得的吸光度测量。该光谱仪采用频率调制光谱法和工作在1.604 µm的近红外二极管激光器来监测30厘米吸收池中的CO₂ - 蒸汽浓度。当监测到吸光度为6×10⁻⁵时，卡尔曼滤波器将光谱仪的信噪比提高了一个数量级。
