Title:
OPTICAL FIBER SCANNER, LIGHTING APPARATUS, AND MONITORING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2015/151593
Kind Code:
A1
Abstract:
An optical fiber scanner (1) is provided with: a long and thin optical fiber (2); driving piezoelectric elements (4A, 4B, 4C), which are provided on the outer circumferential surface of the optical fiber (2), and which make a leading end portion (2b) of the optical fiber (2) generate bending vibration when an alternating voltage is applied to the driving piezoelectric elements; detection piezoelectric elements (5A, 5B), which are provided on the outer circumferential surface of the leading end portion (2b) of the optical fiber (2); and a control unit (6) that controls, on the basis of a voltage generated by means of the detection piezoelectric elements (5A, 5B), the alternating voltage to be applied to the driving piezoelectric elements (4A, 4B, 4C).
