Abstract: front page image
(EN)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.
(FR)On forme un bloc (10) de plusieurs fibres optiques (11) comportant chacune un coeur (12) et une gaine (13). Un tel bloc (10) présente une face (14) d'extrémité d'entrée constituée de la première extrémité des différentes fibres optiques, et au moins partiellement courbe. Ladite face (14) étant pressée contre la surface à mesurer d'un objet à mesurer présentant une surface courbe, il se forme par contact entre la face (14) et la surface à mesurer une image optique ressortant par la face (15) d'extrémité de sortie du bloc, et qui permet d'inspecter la surface courbe de l'objet à mesurer. On réalise ainsi: un procédé d'inspection de la forme de surfaces courbes, un bloc de fibres optiques, et un dispositif d'inspection de surfaces courbe, ledit procédé permettant une inspection facile.
(JA) コア領域12及びクラッド領域13からなる光ファイバ11が複数束ねられ一体に成形されたファイバ光学ブロック10における、各光ファイバの一端から構成され少なくとも一部が湾曲している入力端面14と、被測定対象における曲面形状を有する測定面とを互いに押し付ける。そして、ファイバ光学ブロックの出力端面15から出力され、入力端面と測定面とが接触することにより形成された光学像を用いて被測定対象の曲面形状を検査する。これにより、簡易に曲面形状を検査することができる曲面形状検査方法、ファイバ光学ブロック、及び曲面形状検査装置が実現される。
