    Abstract: In a double beam spectrophotometer, a sample beam is irradiated to a large-sized sample in a substantially vertical direction, and the beam upwardly transmitted through the large-sized sample is reflected by a reflecting mirror and sent to an integrating sphere including a detector. A reference beam irradiated parallel to the sample beam is deflected by reflecting mirrors such that the reference beam goes around the large-sized sample, and guided to the integrating sphere. Thus, a holder is not required to correspond to a size or shape of the sample, and measurement position can be freely changed by moving the sample. Also, in case of utilizing a conventional standard sample chamber, movable reflecting mirrors are inserted in the optical paths to transfer the beams to the standard sample chamber.

    Abstract: A method for segregating qualities of an agricultural product during processing of the product comprises the step of setting a desired range of a measurement value (2). The measurement value represents a property of the product and defines a first quality of the product for which the measurement value is inside the range and a second quality of the product for which the measurement value is outside the range. The method further comprises the step of analyzing (4) the quality of the product that is being processed. The step of analyzing comprises the steps of continuously extracting samples of the product (4a), irradiating each sample by electromagnetic radiation (4d), spatially separating electromagnetic radiation of different wavelengths (4e), and detecting electromagnetic radiation emitted from the sample (4f). The step of detecting produces intensity signals indicative of detected electromagnetic radiation of different wavelengths. The step of analyzing further comprises the steps of determining a sample value of said property of the product from the intensity signals, and determining a measurement value (4g) from at least one sample value. The method further comprises the step of separating the product of said first quality from the product of said second quality on the combine.

    Abstract: In a detector for spectrometry attached to an integrating sphere, a plurality of detection elements having different spectral sensitivity characteristics is arranged side by side in the same plane on a base, and a side cover is provided such that the detection elements receive light. Thus, the measurement light is directly irradiated to the respective detection elements. Accordingly, the detector for spectrometry has a fast response speed and is excellent in the sensitivity characteristics in a wide wavelength region in the near-infrared area.

    Abstract: A structure is described having an optical element having a cylindrical shape adapted for rolling in contact with a surface of a material, a source of electromagnetic radiation coupled into one portion of the cylinder to interact with the surface, and exiting at another portion of the optical element for detection. An apparatus is described for applying electromagnetic radiation to a surface having a cylindrical roller formed from a material transmissive to the electromagnetic radiation; the cylindrical roller adapted for rolling on the surface; and the cylindrical roller adapted for receiving the electromagnetic radiation for reflecting the electromagnetic radiation therein and for directing the electromagnetic radiation towards a detector for detection. The structure and apparatus is directed for use with in-line or real-time process monitoring technology. More particularly to the problem of real-time spectroscopic determination of degree of chemical and physical changes to materials, in particular sheet materials, on a moving fabrication line. In many continuous-feed manufacturing processes involving sheet materials, monitoring the degree of chemical reaction and desiccation is essential and often problematic. Remote sensoring is often not possible due to the speed of material flow, or the necessity for sensor-element/sample contact. Many prior attempts to commercialize real-time monitoring systems have performed marginally or were useful under only a narrow range of circumstances.

    Abstract: A method of calculating optical frequency spectrum for use in an optical-spectrum measuring apparatus for measuring optical spectrum characteristics of a light source. In the method, a bandwidth storage section stores a characteristic of a bandwidth of passed wavelengths with respect to a measuring wavelength of a spectrometer. A CPU obtains a bandwidth of wavelengths with respect to each measuring point in accordance with the stored bandwidth of wavelengths. Then, measured intensities of light at the measuring points are used to add measured values across the measured value in a required range of bandwidth of optical frequencies. Moreover, correction is performed in accordance with a ratio of the bandwidth of wavelengths at each of the measuring points and the intervals of wavelength at the measuring points. Thus, an intensity of light at each of the measuring points is obtained.
