Abstract
A scanning endoscope including an optical fiber scanner that vibrates a distal end of the optical fiber that guides illumination light and emits the illumination light from the distal end thereof, a controller that conducts control for vibrating the optical fiber at a certain driving frequency set according to a resonance frequency of the optical fiber and for controlling amplitude of the vibration so as to be changed at a certain modulation frequency, and a movement detector that detects the resonance frequency of the optical fiber, wherein the controller changes the driving frequency and the modulation frequency at the same rate as the rate of change of the resonance frequency when the resonance frequency of the optical fiber detected by the movement detector changes.
