OPTICAL FIBER SCANNER, ILLUMINATION SYSTEM, AND OBSERVATION APPARATUS |
| 摘要 |
An optical fiber scanner is provided with an illumination optical fiber that guides light and emits the light from a distal end thereof; a plurality of piezoelectric elements that are secured on a side surface of the illumination optical fiber, that have polarizations in radial directions of the illumination optical fiber, and that vibrate the illumination optical fiber when an alternating voltage is applied in the polarization directions; and a vibration suppressing part that suppresses vibrations in the radial directions generated at a position of the illumination optical fiber away from the piezoelectric elements toward a base end. |
