Abstract
In a fiber optic blockformed by bundling and integrating a plurality of optical fiberseach composed of a core regionand a clad region, an at least partially curved input end facecomposed 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 faceof 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.
