光纤扫描器、照明装置和观察装置
摘要：
容易且高精度地进行光纤相对于照明光学系统的定心的组装调整。提供一种光纤扫描器(10)，其具有：照明用光纤(11)；振动传递体(21)，其嵌合在照明用光纤(11)的基端侧；多个压电元件(23)，它们固定在振动传递体(21)上，使照明用光纤(11)振动；以及固定部(25)，其嵌合在振动传递体(21)上的比压电元件(23)靠基端侧隔开间隔的位置，能够经由振动传递体(21)将照明用光纤(11)支承为悬臂状，振动传递体(21)具有：由弹性材料构成的柱状部(33)，其具有能够供照明用光纤(11)插入的贯穿孔，在该柱状部(33)上粘贴有多个压电元件(23)；以及旋转体形状的前端部(35)，其配置在柱状部(33)的前端，以嵌合状态支承照明用光纤(11)，该前端部(35)的径向截面积朝向照明用光纤(11)的前端而逐渐缩小。
摘要（英）：

Provided is an optical-fiber scanner including: an optical fiber; a body fitted on a basal-end side of the optical fiber; piezoelectric elements secured to the body and causing the optical fiber to vibrate; and a securing portion to which the body is fitted at a position that is farther on a basal-end side away from the piezoelectric elements, wherein the body has a columnar portion that is formed of an elastic material to which the piezoelectric elements are attached and that has a through-hole into which the optical fiber can be inserted, and a distal-end portion that is disposed at a distal end of the columnar portion, that supports the optical fiber in a fitted state, and that has a rotator shape in which a cross-sectional area thereof in a radial direction gradually decreases toward a distal end of the optical fiber.
