摘要： In an apparatus for measuring a spectral property such as a total spectral radiant factor of a fluorescent sample, a weight factor is previously calculated by using a standard fluorescent sample in which an index of a spectral property such as a total spectral radiant factor is known. When a spectral intensity distribution of a fluorescent sample to be measured is measured, the measured spectral intensity distribution is corrected similar to a value when the fluorescent sample is illuminated as if the same illumination light when the weight factor is set. As a result, the error component in the measurement result due to the variation of the illumination light in a time period from the setting of the weight factor to the measurement of the fluorescent sample can be reduced.

摘要： The measuring apparatus of the present invention measures the optical properties of a sample containing a fluorescent material by irradiating the sample with light containing a UV component. In the present invention are provided a first light source for irradiating the sample with light containing a UV component, a second light source for irradiating the sample with light which does not contain a UV component, light receiving element for receiving light reflected from the sample irradiated by said light sources, and output means for generating weighting coefficients for weighting the output of the light receiving element during emission by each light source. The optical properties of the sample is calculated based on the output of the light receiving element for a first light source, output of the light receiving element for a second light source, and the respective weighting coefficients. Accordingly, measurement values can be obtained which are equal to values when measurement is accomplished with a standard light source.

摘要： A radiation thermometer has a detector for receiving radiation energy from a target object, and the detector generates an AC signal as a result of movement of a chopper. The AC signal is rectified by a rectifying circuit and the rectified signal is supplied to a microcomputer. On the other hand, temperatures around the detector are detected by a temperature sensor and the temperature of the target object is measured based on those detected values. In addition, the radiation thermometer has various calibration modes other than a measurement mode. In a calibration mode I, calibration data concerning a difference in characteristics of the temperature sensor for each thermometer is obtained. Data for correcting timing for synchronous rectification by the rectifying circuit is obtained in a calibration mode II. Calibration data for calculation of the temperature of the target object is obtained in a calibration mode III. Those calibration data are temporarily stored in a non-volatile RAM so that the temperature of the target object can be calculated by using those calibration data when the measurement mode is selected.
