摘要： The fiberoptic block in accordance with the present invention has an input end face constituted by a combination of a plurality of surfaces each of which is inclined at a slant angle .alpha. by which disturbing light from within the air can be eliminated, whereby an irregularity image with a high contrast can be emitted as usual. Also, it has an output end face perpendicular to the axis of each unit fiber. Accordingly, when the output end face is butted against and secured to an input face of a photodetector, the irregularity image is made incident on the input face of the photodetector so as to be substantially perpendicular thereto, thus allowing a bright irregularity image to be attained. Further, since this fiberoptic block has a form extending from the output end face in a direction perpendicular thereto, it can be attached to the photodetector relatively easily with a high precision.
摘要翻译：根据本发明的光纤块具有由多个表面的组合构成的输入端面，每个表面以倾斜角α倾斜，由此可以消除来自空气中的干扰光，由此具有像往常一样可以发出高对比度。此外，它具有垂直于每个单位光纤的轴线的输出端面。因此，当输出端面抵接并固定在光电检测器的输入面上时，使不规则图像入射到光电检测器的输入面上以与其基本垂直，从而允许获得明亮的不规则图像。此外，由于该光纤块具有从垂直于其的方向从输出端面延伸的形状，因此能够以较高的精度相对容易地安装到光检测器。

摘要： The present invention provides a fiber optical plate comprising (i) a first unit formed by a plurality of first optical fibers which are bundled together and include a core portion and a clad portion and (ii) a second unit optically coupled to the first unit and formed by a plurality of second optical fibers which are bundled together and include a core portion, a clad portion, and an optical absorber made of a material for absorbing the light leaking from the clad portion. The first unit has a first input end surface which is inclined with respect to the center axis of the first optical fibers by an angle at which incident light from within air is prevented from being totally reflected by an interface between the core portion and the clad portion of the first optical fibers and a first output end surface which outputs, of light incident on the first input end surface by way of an object in contact with the input end surface, a light component arriving there after being transmitted through the first optical fibers. The second unit has a second input end surface which is bonded to the first output end surface and a second output end surface which outputs, as an optical image, light arriving there after entering the second input end surface and then being transmitted through the second optical fibers.

The FOP 1 has a conical shape having a height in the optical axis direction; the input end surface 2 configures a side surface of the conical shape; and the output end surface 3 configures a bottom surface of the conical shape. A light incident from the input end surface 2 is output from the output end surface 3 if a palm or the like of a photographic subject is brought into contact with the input end surface 2. The unit fiber 4 has a core 5 for propagating the light which is incident from the input end surface 2, a cladding 6 for covering an external periphery of the core 5, and a light absorbing body 7 for absorbing an incident light while covering an external periphery of the cladding 6. The input end surface 2 is inclined with respect to the optical axis of the core 5 and the angle of inclination is set so that the light incident from air into the core 5 does not generate total reflection at a boundary surface between the core 5 and the cladding 6.

摘要： In a fiber optic block 10 formed by bundling and integrating a plurality of optical fibers 11 each composed of a core region 12 and a clad region 13, an at least partially curved input end face 14 composed of one end of each optical fiber and a measurement surface having a curved surface shape of a to-be-measured object are pressed against each other. Then, an optical image formed by bringing the input end face into contact with the measurement surface and output from an output end face 15 of the fiber optic block is used to inspect the curved surface shape of the to-be-measured object. This allows a curved surface shape inspection method capable of inspecting the shape of a curved surface easily, a fiber optic block, and a curved surface shape inspection apparatus to be achieved.
