Abstract:
(EN) In the present invention, an optical fiber 13 arranged inside a rigid cylindrical member 10 that constitutes a distal portion 8 is inserted and held in a central hole of a ferrule 19 which has top and bottom outer faces to which piezoelectric elements 17a, 17b and the like are attached. In a first region R1 near the base end of a rigid holding member 11 which holds the optical fiber 13 and the base end of the ferrule 19, an optical structure 13a comprising a core 13b and cladding 13c is covered with a flexible cover tube 14a that suppresses excess bending of the optical fiber 13.
(FR) Selon la présente invention, une fibre optique (13), placée dans un élément cylindrique rigide (10) qui constitue une partie distale (8) est insérée et maintenue dans un trou central d'une virole (19) qui présente des faces externes supérieure et inférieure auxquelles sont fixés des éléments piézoélectriques (17a, 17b) et analogues. Dans une première région (R1) à proximité de l'extrémité de base d'un élément de maintien rigide (11) qui maintient la fibre optique (13) et l'extrémité de base de la virole (19), une structure optique (13a) comprenant un noyau (13b) et une gaine (13c) est recouverte d'un tube de couverture souple (14a) qui supprime l'excès de courbure de la fibre optique (13).
(JA) 先端部8を構成する硬質の円筒部材10の内部に配置された光ファイバ13は、上下等の外面に圧電素子17a、17b等が取り付けられたフェルール19の中心の孔に挿通されて保持され、フェルール13の基端と共に光ファイバ13を保持する硬質の保持部材11における基端付近の第1領域R1において、コア13b及びクラッド13cからなる光学構造13aを、可撓性を有し、光ファイバ13における過度の屈曲を抑制する被覆チューブ14aで被覆している。
