Abstract:
A fiber optical block (10) is formed by a plurality of optical fibers (11) each consisting of a core region (12) and a clad region (13). The fiber optical block (10) has an input end face (14) consisting of first ends of the respective optical fibers and curved at least partially. The input end face (14) is pressed against a measurement surface of an object to be measured and having a curved surface. An optical image is formed by contact between the input end face and the measurement surface and is outputted from an output end face (15) of the fiber optical block. By using the optical image, the curved surface shape of the object to be measured is inspected. Thus, it is possible to realize a curved surface shape inspection method, a fiber optical block, and a curved surface shape inspection device capable of easily inspecting a curved surface shape.

Abstract:
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.
