摘要： An active real-time characterization system for monitoring the absorption and/or curing rate of a chemical substance applied to an outer surface of an article under test. Infrared and visible light sources controllably output a pulsed beam of coherent light directed at a particular area on the article under test where the chemical substance has been applied. A series of cameras, including a visible light camera, a visible light second harmonic generation camera, an infrared camera, an infrared second harmonic generation camera, a sum-frequency camera and a third-order camera are configured to receive return beams of light. A processor controls the pulse rate of the light sources and the first visible light source and processes the signals received from the cameras to determine when the chemical substance applied to the outer surface of the article under test has been absorbed or has cured.

摘要： 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.

摘要： An automated system is provided for selectively separating resin pellets having a gel count below a specified maximum from pellets having a gel count above the specified maximum, while the pellets are flowing in a pneumatic conveyor. The separation is based on an essentially continuous measurement in which a laser beam is utilized to detect the number of gels in a film made from pellets withdrawn as a sample stream from the main pellet stream. In response to the gel count measurement, a control signal is established that is utilized to manipulate a diverter valve located in the pneumatic conveyor, which diverts pastic pellet flow between a preferred storage means storing pellets having a low gel count and a secondary storage means for storing pellets having a higher gel count. In operation, a hold up tank is provided between the point from which the sample stream is withdrawn and the diverter valve, so that the plastic pellet flow can be delayed in the hold up tank for the amount of time required for the withdrawn sample stream to be converted into the film, whereby the gel count measurement is representative of the pellets passing through the diverter valve.

摘要： Scanning sensor for measuring properties of continuous flat sheet, that is moving in the machine direction, employs an IR radiation source for directing a beam of incident IR radiation that impinges the sheet. The IR source has elongated lamp filament that generates IR radiation and the corresponding spot size formed on the sheet has elongated dimensions with its long axis being aligned with the machine direction. Aligned with the MD maximizes sensor spatial resolution in the cross direction. The sensor can employ a receiver having rectangular geometry with its long axis being aligned also in the MD. Scanning sensor can operate in the reflective, transmissive, or offset transmission mode to monitor characteristics of flat sheets, particularly of paper or plastic products.

摘要： Radiation scattering is one of the main contributors to the uncertainty of near infrared (NIR) measurements. Enhanced absorption-measurement accuracy for NIR sensors is achieved by using a combination of NIR spectroscopy and time-of-flight techniques to select photons that are the result of a given mean free path within a moving sample target. By measuring absorption as a function of path length or by windowing signals that are attributable to excessive scattering of NIR radiation within the sample, this technique affords the calculation of more accurate and more universal calibrations. The NIR sensor employs short or ultra-short laser pulses to create NIR that is directed to the moving sample and emerging radiation is detected over time. Windowing effectively truncates non-contributing measurements.
摘要翻译：辐射散射是近红外（NIR）测量不确定度的主要原因之一。通过使用NIR光谱和飞行时间技术的组合来选择作为移动样本目标中给定平均自由程的结果的光子，实现NIR传感器增强的吸收测量精度。通过测量作为路径长度的函数的吸收，或者通过对由于样品内的NIR辐射的过度散射而引起的信号的加窗信号，该技术提供了更准确和更通用的校准的计算。 NIR传感器使用短或超短激光脉冲来产生针对移动样品的NIR，并且随着时间的推移检测出新的辐射。窗口化有效地截断了无贡献的测量。
