Abstract:
An image information read-out system, comprising:a test piece holder portion which holds a test piece having specific binding substances which have been hybridized with an organism-originating substance labeled with fluorescent dye, the specific binding substances being disposed on a plurality of surfaces of the test piece; an exciting light source which emits exciting light for exciting the fluorescent dye; photoelectric read-out means which photoelectrically reads out fluorescence emitted from the fluorescent dye upon exposure to the exciting light; scanning means which has an optical head for projecting the exciting light onto the test piece, for leading fluorescence, which is emitted from the fluorescent dye and travels back towards the exciting light being projected onto the test piece, to the photoelectric read-out means, and for causing the exciting light to scan the test piece; and a controller which controls the exciting light source, the photoelectric read-out means, and the scanning means so that fluorescence, emitted from the specific binding substances upon exposure to the exciting light, is detected for each of the plurality of surfaces of the test piece wherein the plurality of surfaces are arranged in a direction of thickness of a substrate of the test piece, and wherein the specific binding substances are positioned such that they do not interfere with each other.
