摘要： A fingerprint input apparatus includes a light source 2 for emitting light and a fiber optic plate 3 having a finger contact surface with which a finger 1 is brought into contact in order to pick up a fingerprint image of the finger 1. The light from the light source 2 is at first introduced into an inside of the finger 1, is scattered within the inside of the finger 1, and comes out of the finger through the surface of the finger 1 as outgoing light. By the use of the outgoing light, the fingerprint image is formed. The light source 2 is disposed so that the light from the light source 2 enters into a substantial center of a part of the finger 1 including a first joint on a palm side and that the light source 2 is contacted with the finger 1.

摘要： The fiber optic device in accordance with the present invention has a structure in which two fiber optic members are connected together, end faces thereof opposing each other. The input-side fiber optic member comprises cores extending in a predetermined direction and a light absorber surrounding the cores. The output-side fiber optic member comprises cores extending in a predetermined direction, and a cladding surrounding the cores. The input end face of the input-side member is inclined with respect to core axes therein. In this device, the angle of inclination of the input end face of the input-side member or the angle formed between the output end face of the output-side member and each core axis in the output-side member can be set to a value relatively near to 90.degree.. Accordingly, this device can be attached to a photodetector with relative ease. Also, a light receiving member formed by this attachment is relatively compact.

The first assembly is obtained by integrating a plurality of optical fibers by bundling, and has first and second end faces formed obliquely to the optical axis of the optical fibers contained in it. The second end face has small recesses and projections to scatter light emerging from it. The second assembly is obtained by integrating a plurality of optical fibers by bundling, and has first and second end faces substantially intersecting perpendicularly to the optical axis of the optical fibers contained in it. The first end face of the second assembly is bonded to the second end face of the first assembly.

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.

摘要： A tapered FOB (20) obtained by forming optical absorbers on the outer surfaces of fibers and bundling these fibers is joined to a slant FOB (10) obtained by bundling fibers, and a CCD (60) is arranged at the output end face of the tapered FOB (20). The slant angle (.beta..sub.0) of a detection surface (11) of the slant FOB (10) on which a fingertip is to be placed is set to an angle at which background light incident from air on the slant FOB (10) is not reflected as total internal reflection at the interface between the core and cladding of the slant FOB (10). The slant angle (.beta..sub.1) of the tapered FOB (20) is set such that background light reaching the tapered FOB (20) becomes incident at the interface between the core and the cladding at an angle smaller than the critical angle at which total internal reflection occurs. Unwanted background light and illumination light are eliminated, and the S/N ratio of a fingerprint image to be detected can be increased.
