    Abstract: 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.

    Abstract: There is described a method of determining the UV fluence received by a fluid. The method comprises the steps of: (a) irradiating the fluid at an unknown UV fluence; (b) measuring the fluorescence of a test sample of the fluid after irradiation in Step (a) to produce a test signal proportional to the concentration of a prescribed fluorescent composition of matter comprised in the test sample; and (c) determining the value of the unknown UV fluence by comparing the test signal to a calibration curve of a control signal proportional to concentration of the prescribed fluorescent composition of matter in the fluid as a function of applied UV fluence. There is also described a system for determining the UV fluence received by a fluid being treated in UV fluid treatment system comprising at least one UV source. The system comprises: (a) a radiation-transparent vessel for receiving a test sample of the fluid after irradiation of the fluid at an unknown UV fluence; (b) a fluorometer for measuring the fluorescence of the test sample received in the radiation-transparent vessel to produce a test signal proportional to the concentration of a prescribed fluorescent composition of matter comprised in the test sample; and (c) a controller configured to determine the value of the unknown UV fluence by comparing the test signal to a calibration curve of a control signal proportional to concentration of the prescribed fluorescent composition of matter in the fluid as a function of applied UV fluence.

    Abstract: The refractive index of a test object is measured with high precision.The present invention relates to a method for measuring a refractive index of a test object by splitting light from a light source into test light and reference light and measuring interference light resulting from interference between the reference light and the test light transmitted through the test object. In the method, the test object is arranged in a medium whose group refractive index is equal to a group refractive index of the test object at a particular wavelength, interference light is measured, the particular wavelength is determined based on a wavelength dependence of a phase difference between the test light and the reference light, and the group refractive index of the medium corresponding to the particular wavelength is calculated as the group refractive index of the test object corresponding to the particular wavelength.
