Abstract: A spectroscopic sensor for measuring flat sheet product is disclosed. The disclosed sensor uses a combination of spectrometers and single-channel detectors and filters together with a broadband source of illumination to optimally measure multiple properties of a flat sheet product. A spectrometer is used to measure over a spectral range where an easily configurable set of wavelength channels is needed and where the signal-to-noise ratios and spectral resolutions of the channels are consistent with the spectral range and number of pixels of the spectrometer; while one or more single channel detector and filter combinations are used to measure, with high signal-to- noise ratio, at specific wavelengths within or outside the spectral range of the spectrometer(s). Therefore, the single channel detectors can be used to complement the information provided by a spectrometer or to extend the working range of a spectrometer by providing single wavelength measurements anywhere in the visible, near-IR or mid-IR spectral regions.
Abstract translation: 公开了一种用于测量平板产品的光谱传感器。 所公开的传感器使用光谱仪和单通道检测器和滤波器的组合以及宽带光源来最佳地测量平板产品的多个性质。 光谱仪用于在光谱范围内测量，其中需要容易配置的一组波长信道，并且其中信道的信噪比和光谱分辨率与光谱仪的光谱范围和像素数量一致; 而一个或多个单通道检测器和滤波器组合用于以高信噪比测量在分光器的光谱范围内或外的特定波长。 因此，可以使用单通道检测器来补充光谱仪提供的信息，或通过在可见光，近红外或中红外光谱区域中的任何地方提供单个波长测量来扩展光谱仪的工作范围。

Abstract: Infrared spectroscopy techniques are employed to measure (i) the moisture level in both the sheet of wet stock and the papermaking machine clothing on which the sheet is supported and (ii) the moisture level in the clothing alone as a separate layer of material. Differential measurement thus yields the moisture content of the sheet of wet stock alone. Changes in the moisture level in the clothing at the press section can be correlated with corresponding changes in the quality or physical property of the paper produced. Both fixed point and scanning IR sensors are strategically positioned in the press section to generate machine direction and/or cross machine direction water profiles for process control.

Abstract: A system includes a first sensor unit having multiple solid-state light sources (202a-202n) each configured to generate light at one or more wavelengths, where different light sources are configured to generate light at different wavelengths. The first sensor unit also includes a mixer (204, 302a-302n, 304, 402a-402m) configured to mix the light from the light sources and to provide the mixed light to a web (108) being sampled. The first sensor unit further includes a controller (258a) configured to control the generation of the light by the light sources. The system also includes a second sensor unit comprising a detector (206) configured to measure mixed light that has interacted with the web. The second sensor unit could also include a second controller (258b) configured to determine one or more characteristics of the web (such as moisture content and fiber weight) using measurements from the detector.

Abstract: A spectroscopic method (100) and spectroscopy system (200) therefrom for analyzing samples (298). A sample includes a first chemical component that has a characteristic first absorption peak is provided (101). The sample is irradiated (102) in a measurement waveband proximate to the first absorption peak, and at a first and a second reference waveband where the first chemical component lacks characteristic absorption features. Reflected or transmitted detection data is obtained (103) including a measured power proximate to the first absorption peak and first and second reference powers at the reference wavebands. A plurality of different waveband ratios are evaluated (104) using pairs of detection data to generate a plurality of measured waveband ratio values. A parameter of the first chemical component is then determined (105) by evaluating a multidimensional polynomial calibration equation that relates the parameter of the first chemical component to the plurality of different waveband ratios by substituting the measured waveband ratio values into the calibration relation.

Abstract: A method includes measuring (508) a caliper of a sheet (108) of material using a caliper sensor (200, 300) having first and second sensor modules (202-204, 302-304). The method also includes adjusting (514) the caliper measurement based on a transverse displacement between a first sensor component in the first sensor module and a second sensor component in the second sensor module to generate a corrected caliper measurement. Adjusting the caliper measurement can include applying a corrector function that adjusts the caliper measurement based on the measured transverse displacement. The corrector function can be identified by repeatedly creating misalignment between the first and second sensor components, measuring a known distance using the caliper sensor, and identifying an error between the measurement of the known distance and the known distance.
