Abstract: The present subject matter is direct to methodologies for calibrating data obtained from an optical analysis system. An initial calibration matrix of sampled analyte concentrations is modified using mean-centering techniques and selection of low and high analyte concentration spectra to produce a two-point calibration. A modified calibration matrix is produced by generating a non-linear calibration matrix by multiplying the initial calibration matrix by the two-point calibration. In an alternate embodiment, an initial multivariate optical element design is modified by iteratively adjusting the design based on standard error of calibration determination based on non-linerly fitted functions.

Abstract: Automatic zeroing apparatus zeroes an infrared gas analyzer automatically upon the occurrence of preselected conditions to indicate zero in the absence of absorption of infrared radiation by a gas mixture being analyzed. The gas analyzer has a sample cell (11) for containing a gas mixture to be analyzed. Infrared radiation directed through the sample cell (11) is detected at a preselected wavelength to produce a detection signal. A signal processor outputs a signal systematically related to the difference between the detection signal and a reference signal. For zeroing the sample cell (11) is filled with gas substantially nonabsorbent of infrared radiation at the respective characteristic wavelength. A comparator produces an error signal when the output signal differs from zero. A gain control (DAC 21) automatically controls the signal level of the detection signal to reduce the output signal substantially to zero with the nonabsorbent gas filling the sample cell (11). The preselected conditions may include the passage of a predetermined time and a temperature drift beyond a predetermined limit.

Abstract: A fiber optic fluid opacity sensor includes a light source (12) transmitting light to dividing means (14) for providing a sample light signal (18) and a reference light signal (20) to dual photodetectors (26, 28). Sample and reference optical pathways (19, 21) are defined by optical fibers (18, 20) spaced apart from and axially aligned with the photodetectors (26, 28) at a predetermined distance. Signal processing means (30) takes the log ratio output of the signals from the photodetectors (26, 28) for cancelling the effect of light source drift since the same source (12) is common to both for measuring the light transmission and determining opacity therefrom. A sample probe (40) contains the photodetectors (26, 28) and the sample and reference optical pathways (19, 21). The light source (12) and the signal processing means (30) are situated outside of the probe (40) and by virtue thereof outside of the sample process line (48).

Abstract: Apparatus for controllably admitting a sample volume of engine exhaust into a bifurcated, closed-loop opacity chamber and wherein the exhaust sample is controllably directed away from the internal optics via symmetric flow inducing air guides. A pulsed light source is controllably directed through the opacity chamber and exhaust sample and the detected light is compared to a reference level so as to determine a relative measure of the sample's opacity. Attendant control circuitry permits the selected display of corresponding sample opacity and density values.

Abstract: 【解決手段】本発明は、試料の検査に用いられる検査システムの検出範囲を拡張する検査システムと方法に関する。 一実施態様に準じ、検査システムは、散乱光を受け取り、出力信号に変換するように結合された複数のステージを有する光検出器と、少なくとも一つのステージを飽和させることで、それによって光検出器が非線形領域で作動するように強制し、光検出器の検出範囲（従って、検査システムの検出範囲）を拡張するように接続された電圧分割ネットワークを備え得る。 このことは、光検出器が非線形的に作動することを強制する。 しかしながら、測定の不正確さは、少なくとも一つのステージを意図的に飽和させることで生成され得るあらゆる非線形効果を除去するように光検出器の出力を較正することで避けられる。 一例に於いて、光検出器の出力を散乱光の実際量に変換するように較正中に値表を生成可能である。
