OPTICAL FIBER SCANNER, ILLUMINATION DEVICE, AND OBSERVATION APPARATUS

WIPO Patent Application WO/2016/075777

A1

The present invention makes the assembly and adjustment of centering an optical fiber with respect to an illuminating optical system easy and highly precise. Provided is an optical fiber scanner (10) equipped with: an illuminating optical fiber (11); an oscillating transmitter (21) into which the base end of the illuminating optical fiber (11) is fitted; multiple piezoelectric elements (23) that are fixed on the oscillating transmitter (21) and are for oscillating the illuminating optical fiber (11); and a fixed part (25) into which the oscillating transmitter fits at a position shifted toward the base end with respect to the piezoelectric elements (23) of the oscillating transmitter (21) and which is capable of supporting the illuminating optical fiber (11) in a cantilevered fashion via the oscillating transmitter (21). The oscillating transmitter (21) comprises: a columnar part (33), which has a through hole into which the illuminating optical fiber (11) can be inserted and which is obtained from an elastic material on which the multiple piezoelectric elements (23) are bonded; and a tip part (35), which is disposed on the front end of the columnar part (33) to support the illuminating optical fiber (11) in a fitted state and which has a shape of a solid of revolution, the radial direction cross-sectional area of which gradually decreases towards the tip of the illuminating optical fiber (11).
