摘要： A reflection characteristic measuring apparatus for measuring a characteristic, such as a gloss, of a sample surface. The apparatus includes at least one illuminator for illuminating a sample surface to be measured with light and a plurality of light receiving sections which are arranged axially symmetrically to each other with respect to a normal to an intended object surface and which output two-dimensional light receiving data. A deriving section derives a characteristic of the sample surface such as gloss based on a weighted average obtained by applying a weighting factor to each of the light receiving data outputted from the light receiving sections.

摘要： A measurement controller is electrically connected with light emitting circuits and controls the light emission of light sources. A calculator calculates reflection characteristic measurement values of a measurement object corresponding to the respective illuminators. Undetermined coefficients of a Gaussian function stored in a memory are determined using the calculated reflection characteristic measurement values, and errors created by an angle of inclination of a normal to a surface of the measurement object with respect to a center axis of a main body are corrected using the Gaussian function whose undetermined coefficients are determined to obtain corrected reflection characteristic values. Since a measurement result is corrected according to the angle of inclination of the main body with respect to the object surface, this enables a high-precision colormetry.

摘要： An ellipsoidal mirror having an axis of rotational symmetry is disposed so that a first focal point thereof is positioned in vicinity of a measurement area of a light source to be measured. The ellipsoidal mirror reflects parallel light beams from the measurement area onto an optical focal plane on which the reflected light beams are focused, whereby a luminous intensity distribution image of the measurement area is formed on the optical focal plane. The luminous intensity distribution image is directed via a relay lens system onto a sensing surface of an image pickup unit. A distribution of luminous intensity of the measurement area is obtained based on the luminous intensity distribution image.
