摘要： In a calibration reference light source and a sensitivity calibration system using the same, a plurality of single-wavelength light sources for emitting reference lights having mutually different single-wavelengths are used instead of a black body radiation source for radiating a white light, and not only the intensities of the single-wavelength reference lights, but also the wavelengths thereof are measured to obtain sensitivity correction coefficients of intensity-to-radiance conversion data. Thus, obtained reference radiance are highly reliable and sensitivity correction of spectrophotometers and spectral illuminometers can be performed with high accuracy and reliability at a user side, whereby the calibration reference light source and the calibration system using the same can be obtained at low cost.

摘要： In an optical property measuring method and an optical property measuring apparatus, a spectral transmittance characteristic of a reference colored layer prepared as a reference is corrected based on a measured spectral reflection characteristic of a colored layer, and the spectral reflection characteristic of the reference colored layer. With this arrangement, information on the measured spectral transmittance characteristic of the colored layer can be obtained with sufficient precision in conformity with a printing condition of a sample to be measured. Thus, colorimetry of a printed color of a fluorescent sample i.e. a colored surface on a fluorescent substrate can be accurately performed by using the corrected spectral transmittance characteristic of the reference colored layer.

摘要： In a polychrometer and a method for correcting stray light of the polychrometer, relative spectral (inter-pixel) distribution of stray light independent of a spectral distribution of an incident light is obtained, intensity coefficient of the stray light is calculated according to spectral (inter-pixel) distribution of the incident light, spectral (inter-pixel) distribution of the stray light included in a spectral (inter-pixel) distribution of an incident light is estimated and corrected. Thus, the stray light can be more accurately corrected as compared with a conventional case where stray light distribution is directly estimated from an incident light.

摘要： An optical property measuring apparatus and an optical property measuring method of the invention determine a specified optical property of a sample by using a distribution function indicating a distribution of the amounts of reflected light incident on an optical sensor along a coordinate axis defined on a light-sensing surface of the optical sensor. Therefore, even when the optical sensor is a light-sensing device provided with a relatively small number of photosensitive elements, it is possible to measure the specified optical property regardless of a position error of the sample, if any, and reduce errors in measurement values caused by such a sample position error.

摘要： An output current from each pixel sensor can be extracted at an arbitrary ratio by a current divider. An arithmetic control unit sets the dividing ratio in correspondence to a color matching function. The current components are added together by a summing amplifier so that a signal corresponding to a tristimulus value is composed and then converted into a digital signal. That is, weighting by weight factors corresponding to color matching functions of CIE 2-degree observer is performed in a stage of analog signal processing.

摘要： A correction LED is provided to illuminate a light receiving sensor array, and a calculation controlling circuit calculates correction values at the respective illuminance levels based on sensor output levels expected at the respective illuminance levels and actual sensor output levels while successively turning the correction LED on at a plurality of illuminance levels whose illuminance ratios are at least known, and corrects a sensor output level by the corresponding correction value to obtain a measurement output at the time of an actual measurement. The discontinuity of an input/output characteristic resulting from the switching of gains of an amplifier for amplifying a photocurrent and the non-linearity caused by the saturation of the photoelectrically converting characteristic of the optical sensor and the exponential characteristics of the optical sensor and the amplifier can be corrected without employing a large-scale construction such as a bench. The non-linearity can be highly precisely and efficiently corrected in a measuring apparatus realized as a spectral luminometer or a spectral colorimeter without requiring a special facility.
