Abstract: A color luminance meter 1 is provided with a polychrometer 4 as a spectral optical system including a light receiving sensor array 43, a signal processing circuit 5 and an operation control unit 6. The operation control unit 6 carries out calculations to obtain characteristics of a measurement light based on a specified spectral responsitivity, using light reception signals and specified weighting coefficients. The spectral responsitivities of light receiving sensors constructing the light receiving sensor array 43 are selected such that B≧5 nm and A/B lies within a range of 1.5 to 4.0 when A, B denote the half power band width of the spectral responsitivities and a center wavelength interval of the spectral responsitivities. Accordingly, there can be provided a light measuring apparatus capable of maximally suppressing errors to highly precisely measure color luminance values and the like even in a measurement of a light lying in a narrow band such as a monochromatic light.

Abstract: An imaging system is disclosed comprising an illuminator which produces illumination of any desired pure wavelength or of any selected mixture of pure wavelengths simultaneously, which illuminates a sample without spatio-spectral artifacts using illumination optics designed for that purpose; imaging optics, which form an image of the sample at a detector or viewing port; and a detector. This enables imaging the complete spectral image cube for a sample by taking sequential images while illuminating with a series of pure wavelengths, with greater ease and economy than by means of tunable filters, interferometers and the like. It further enables imaging while the sample is illuminated with a precisely controlled mixture of illuminant wavelengths, so that the image presented to the detector is a linear superposition of the sample properties at many wavelengths. This enables taking images of a sample' that directly measure the weighted spectral properties such as projection pursuit vectors, principal components, and the like. Data acquisition is enormously simplified, and speed is increased by one to two orders of magnitude over existing techniques. This is of great benefit in pathology, immunohistochemistry, Pap smear analysis, endoscopy, counterfeit detection, quality control, and other areas where one wishes to measure a spectral index of a living or inert sample.

Abstract: In measuring a spectral irradiance distribution of light, light is irradiated to n (natural number) light-transit sections, which respectively have n kinds of given optical characteristic coefficients, and s (natural number) optical sensors, which respectively have s kinds of given spectral sensitivities, receive the light via the n light-transit sections and detects individual responses for the received light. Then a calculating section calculates m (natural number) spectral irradiances for m kinds of wavelengths as a spectral irradiance distribution based on linear formulae established between the optical characteristic coefficients, the spectral sensitivities, (nnulls) responses for the light obtained by the s optical sensors, and the spectral irradiance distribution of the light.

Abstract: A calorimetric apparatus includes an image pickup unit, an optical unit, a plurality of optical bandpass filters, a switching unit, an arithmetic processing unit, and an optimum filter selection unit. The image pickup unit picks up the image of light from a target object. The optical unit allows the light from the target object to form an image on the image pickup unit. The plurality of optical bandpass filters are arranged between the target object and the image pickup unit and have pass bands different from each other. The switching unit switches the plurality of optical bandpass filters. The arithmetic processing unit performs arithmetic processing for colorimetry on the basis of the spectrum data of the target object whose image is picked up. The optimum filter selection unit selects, from the plurality of optical bandpass filters, a filter suitable for colorimetry by the arithmetic processing unit.

Abstract: Apparatus for monitoring, converting and calibrating the spectra displayed by a colored object, using wavelength dispersion provided by a variable wavelength filter. The apparatus may serve as a spectrophotometer, as a colorimeter, or as a spectroradiometer or other device that monitors and calibrates a light signal by decomposition of the signal into a wavelength distribution.
