    Abstract: An optical characteristic measuring apparatus and an optical characteristic measuring method of the invention are an optical characteristic measuring apparatus and method for obtaining a predetermined optical characteristic such as a color value or a total spectral radiation factor of a measurement object. A spectral intensity distribution of predetermined ambient light entering through a measurement opening is measured and stored prior to measurement of the optical characteristic. In measuring the optical characteristic, an optical characteristic in a condition that actually measured ambient light is used as an observation light source is obtained, with use of the stored spectral intensity distribution of ambient light.

    Abstract: Color measurement instrument (10) including an integrating sphere (12), a beam splitter (16), a video camera (18), and a spectrograph (20). The beam splitter (16) is aligned with the viewing port (32) of the spectrophotometer to deliver the light reflected from the sample (S) to both the video camera (18) and the spectrograph (20). The video camera (18) provides an image of the position of the sample (S) with respect to the viewing port (32) of the sphere (12), enabling the visual observation and evaluation of the sample position prior to use of the spectrophotometer.

    Abstract: The invention relates to a grating optical sensor comprised of a lens (1) that reproduces an object space, of a diffractive hexagonal 3D grating optical modulator (4) in the image plane (5) of the lens (1), of a photoelectric receiver device (8), which is arranged in the near field behind the modulator (4) in accordance with the centrosymmetrically trichromatic diffraction orders (R, G, B), and of an evaluation device for the electrical signals generated by the individual receivers (8). The invention is characterized in that at least one light diffusion glass (9) is arranged in the pupillary plane of the lens (1) or in a pupillary plane conjugate thereto. The inventive sensor is used for conducting chromatometries with a color constancy performance via a thermal radiation source (17), which modifies the grating constants of the 3D grating (4) for a new white standard value.
