Abstract: PURPOSE:To use lightguides by simply switching the lightguides comprising photodetectors having the adequate aligning pitches in response to the size of a substance under inspection. CONSTITUTION:Lightguides 8a and 8b are arranged in a plurality of stages along the radiating direction of the light beam from an optical scanning part 4. Each lightguide 8a which is located between the optical scanning part 4 and the most separated lightguide 8b from the optical scanning part 4 is linked to a moving mechanism 9 which is made to extend and retreat with respect to the scanning plane of the light beam. The lightguides 8a and 8b are set so that the aligning pitches of photodetectors 10a and 10b which are aligned in the array pattern become longer as the photodetectors are separated from the optical scanning part 4 to the more remote parts.

Abstract: PURPOSE:To obtain the phantom which allows easy setting to a desired absorbance and shape by incorporating either or both of a light scattering material and dye into a rubberlike elastic material and controlling the amt. of the light scattering material to be incorporated. CONSTITUTION:The phantom is formed by incorporating the light scattering material and the dye into the rubberlike elastic material. The phantom 20a of the 1st layer and the phantom 20b of the 2nd layer are integrated and the phantoms 20a, 20b vary in the amts. and kinds of the light scattering material and dye to be incorporated. A mixture composed of silicone rubber and catalyst is used as the rubber-like elastic material and kaolin as the light scattering material is incorporated therein. Phthalocyanine blue is incorporated as the dye therein. The mixture composed of these raw materials is sufficiently stirred and is vacuum-defoamed; thereafter, the mixture is poured into a mold and is cured to form the phantom 20a. The phantom 20a is then fixed into a mold and after the raw materials are vacuum-defoamed, the raw materials are poured into the mold and are cured to form the phantom 20b. The phantom of a multilayered structure having different absorbarsces is obtd. if the phantoms are repeatedly laminated and the kinds and amts. of the light scattering material and dyes of the respective layers are varied.

Abstract: PROBLEM TO BE SOLVED: To determine ingredient concentration levels in a specimen more accurately by considering the nonlinear relationship between ingredient concentration levels in the specimen and measured data. SOLUTION: In this method, light is projected on an organism, and an image is recovered by using a 2D detector from the light reflected by the organism. The nonlinear relationship between tissue data and measured data is determined in advance, and the relationship is utilized to gather further data about the tissue. Now that the nonlinear relationship is taken into consideration, more accurate data is obtained about the tissue of the organism.

Abstract: PROBLEM TO BE SOLVED: To measure with a plurality of wavelengths and/or wavelength ranges in an optical apparatus for measuring a living matter. SOLUTION: High-speed measurement of two-dimensional measured image data with the plurality of wavelengths and/or wavelength ranges is realized by reducing the number of filters.

Abstract: PROBLEM TO BE SOLVED: To obtain a clear distribution image of an organismic tissue by removing influence by shade and shadow in an optical measuring device for a organism. SOLUTION: Only distribution image data on an organismic tissue is extracted by removing an image component by shade and shadow from plural wave length image data detected by a two-dimensional detector to obtain a clear distibution image. A first mode forms reference image data having only shade/shadow information on a subject, corrects measuring image data by this reference image data, and takes out only object distribution image data. A second mode measures the subject in the plural image pickup directions or the illuminating direction, and calculates the distribution image data by correcting a shade/ shadow component by reconstituting obtained plural image data.
