  • Patent number: 7773224
    Abstract: A system (200) and method (800) for determining whether a sample object (203) has a color that is within a predetermined range is provided. The system (200) includes a light source (201) capable of projecting lights having different light wavelength spectrum upon the sample object (203). A controller (222) causes the light source (201) to project a first light wavelength spectrum upon the sample object (203), then another, then another, and so forth. While each light is projecting upon the object, a monochromatic image capture device (202) captures an image having luminous intensity information. The luminous intensity information, or a subset thereof selected by an image selection tool (232) is then compared to the statistical range, which is derived from a plurality of images taken of a reference object (403).

  • Patent number: 7728970
    Abstract: A method for determining a mixture composition of a plurality of fluorescent materials includes steps of calculating a first function, calculating a second function and determining a secondary mixture composition of the plurality of fluorescent materials. The first function is calculated by comparing an objective spectrum of an objective light with a reference spectrum of a reference light. The second function is calculated by comparing a primary spectrum of the plurality of fluorescent materials mixed at a primary mixture with the reference spectrum composition. The secondary mixture composition is determined on the basis of the result of comparison between the first function and the second function.

  • Patent number: 7692793
    Abstract: The specification describes an optical wavelength monitor/analyzer that uses a cost effective wavelength reference source. The wavelength reference source is a nominally fixed wavelength laser with inherent tunability over a very limited wavelength range, i.e. a few nanometers. Tuning is effected by changing the temperature of the laser. The limited range is useful for making multiple wavelength measurements in the context of analyzing wavelength drift in tunable optical filters.

    Abstract: A color inspection system capable of making a determination on pass or failure with accuracy equivalent to that for the case of a visual inspection even in the case of inspecting various textile products as measurement targets, such as raised cloth, cloth with printed patterns such as a marbled pattern, moire pattern and detailed pattern is provided. With the color inspection system, an illuminant is set to shine a light on the surface of a textile product placed on the top surface of a measuring platform to thereby make measurements from a direction at an angle of 45 degrees from the surface of a measuring region of the textile product by use of a spectroradiometer of a measuring unit. The spectroradiometer is provided with a wide range lens attached thereto to thereby expand a measuring region. The results of measurement by the spectroradiometer are inputted to an information processor of a determination unit.

    Abstract: An apparatus and a method for evaluating control marks on printing materials by an optical sensor connected to a computer, which interprets overshooting of a predefined intensity threshold as it registers the printing material being a line of a printed control mark. The apparatus is distinguished by the fact that the control mark is registered by a color measuring instrument and that the intensity threshold of the optical sensor is calculated by the computer in dependence on the measured color value registered by the color measuring instrument.

    Abstract: The invention relates to a broadband Terahertz (THz) radiation generation and detection system and method. THz radiation is generated by optical rectification of an ultrashort pump pulse of a first wavelength having a duration in the picosecond- or sub-picosecond range in a first nonlinear optical crystal. The THz radiation is detected by electro-optic sampling or another appropriate method of a probe beam having a second wavelength in a second nonlinear optical crystal. According to the invention, at least one of the following conditions is fulfilled: a) the first wavelength is different from the second wavelength; b) the material of the first nonlinear optical crystal is different from the material of the second nonlinear optical crystal.
