    Abstract: An exemplary method for measuring a refractive index of a substance being measured through an optical window, includes arranging the optical window in contact with the substance being measured, directing light to the interface of the optical window and substance being measured, where part of the light is absorbed by the substance being measured and part of it is reflected from the substance being measured to form an image, in which the location of the boundary of light and dark areas expresses a critical angle of the total reflection dependent on the refractive index of the substance being measured, and examining the formed image. Light is directed on a first structure and to desired angles on an interface between the optical window and substance being measured. Light reflected from the interface of the optical window and substance being measured is directed on a second structure.

    Abstract: The present invention discloses a light source with uniform chromaticity and luminance and a color sensor having the same. The light source includes multiple LED devices, a primary light guide plate assembly and a secondary light guide plate assembly. The chromaticity and luminance of light emitted from the LED devices are uniformized for the first time in the primary light guide plate assembly and then guided into the secondary light guide plate assembly for the secondary chromaticity and luminance uniformization, to thereby act as the light source of the color sensor. Therefore, the light source not only provides better chromaticity and luminance uniformization effects, but is further qualified as the standard illuminant D65, thereby enabling more precise color sensor inspection results.

    Abstract: A spectroscopic characteristics acquisition unit includes a light emitting unit to illuminate a measurement target; a lens array including lenses to receive reflected light reflected from the measurement target; a light blocking member having a pinhole array including openings; a focusing unit to focus light coming from the pinhole array; a diffraction unit to diffract the light to different directions depending on wavelength of light received by the focusing unit; and a light receiving unit to receive the reflected light diffracted by the diffraction unit. The light receiving unit includes a spectroscopic sensor array having spectroscopy sensors including pixels. Each of the lenses constituting the lens array corresponds to one of the openings of the pinhole array. The numerical aperture NA of the lens in the arrangement direction in the lens array satisfies the formula NA>sin(θmax) with respect to the maximum angle of view θmax of the focusing unit.
