OPTICAL FIBER SCANNER INCLUDING A RESONANCE FREQUENCY MODULATION UNIT

摘要

The present invention relates to an optical fiber scanner including a resonance frequency alteration means including: a driver (100) for applying a driving force to an optical fiber (200); the optical fiber (200) installed on the end part of the driver (100) in the form of a cantilever; a mass (300) installed on the end part of the optical fiber (200); and the resonance frequency alteration means (400) including a first auxiliary structure (410) installed on the optical fiber (200) to differently alter the driving force applied to the optical fiber (200) to the X and Y directions individually so as to have a resonance frequency of the optical fiber (200) divided into the X direction and the Y direction differently.
