OPTICAL FIBER SCANNER, ILLUMINATION DEVICE, AND OBSERVATION DEVICE

WIPO Patent Application WO/2017/094050

A1

With the purpose of stabilizing the vibration state of an optical fiber by precisely placing the optical fiber with respect to piezoelectric elements, this optical fiber scanner (6) is provided with: a long, thin optical fiber (9) that guides light; a vibration transmission member (10) that includes a through-hole (10a) through which the optical fiber (9) is passed; piezoelectric elements (12A, 12B) which are affixed to the outer surface of the vibration transmission member (10), which undergo stretching vibration in the longitudinal direction of the optical fiber (9) when alternating voltage with a prescribed frequency is applied, and which thereby cause the optical fiber (9) to generate flexural vibration in a direction that intersects the longitudinal direction; and a securing section (11) that secures the vibration transmission member (10). The vibration transmission member (10) is provided with: a retaining surface (10c) that comprises a flat surface to which the piezoelectric elements (12A, 12B) are affixed; and a contact surface (10b) that comprises a flat surface parallel with the retaining surface (10c), that is disposed on at least part of the inner surface of the through-hole (10a), and that makes contact with the outer surface of the optical fiber (9).
