摘要： The invention provides a method for determining oil contents in rocks. The method comprises steps of: measuring a plurality of calibration oil samples having different oil contents, and acquiring a holographic fluorescence spectral intensity corresponding to the calibration oil samples; acquiring a fit relation between the holographic fluorescence spectral intensity and the oil contents of the calibration oil, according to the oil contents of the plurality of calibration oil samples and a plurality of three-dimensional fluorescence spectral intensities corresponding thereto; adding a certain amount of the calibration oil after dilution to rocks to be measured, acquiring a sample of the rocks to be measured and performing a holographic fluorescence measurement of the rock sample to be measured; and introducing the holographic fluorescence spectral intensity of the rock sample to be measured to the fit relation, thus an oil content of the rock sample to be measured is obtained. Accordingly, oil is detectable together with an organic solvent without volatilization of the organic solvent, which not only saves time, but also address a low-detection-limit problem for oil content resulting from volatilization of oil when the organic solvent is volatilized in the conventional method.

摘要： An oxygen number density or concentration sensor including a sampling luminescent oxygen probe located in a fluid environment, and a gas impermeable enclosure located in the fluid environment and a reference luminescent oxygen probe located within the gas impermeable enclosure, wherein the sampling and reference luminescent oxygen probes are formed by an ideal PSP. A predetermined fixed oxygen number density or concentration is provided within a medium contained in the gas impermeable enclosure. A detector receives signals corresponding to luminescent emissions of the sampling and reference probes. A processor determines a number density or concentration of oxygen in the fluid environment from a signal generated at the sampling probe with reference to an oxygen number density or concentration dependent signal generated at the reference probe.

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。

摘要： There is provided a test method for analysing a body fluid in which a test tape is used in a test device in order to successively provide analytical test fields stored on the test tape, wherein body fluid is applied by a user to the test field provided at a time and the said test field is photometrically scanned using a measuring unit of the device to record measurement signals. In order to increase the measurement reliability, it is proposed that a control value is determined from a time-dependent and/or wavelength-dependent change in the measurement signals and that the measurement signals are processed as valid or discarded as erroneous depending on the control value.
