Abstract: An illumination method includes causing coherent light from a light source to enter a multimode propagation path via an incidence surface, relatively oscillating the light incident on the incidence surface and the incidence surface so as to temporally change at least one of an incidence position and an incidence angle of the light on the incidence surface, and radiating the light that has propagated through the propagation path onto a target.

Abstract: Provided is a scanning endoscope system including: an illumination-light emitting portion that is inserted into a body of a patient and that emits illumination light emitted from a light-source portion toward an imaging subject in the body in a spot-like manner; a light scanner that scans the illumination light on the imaging subject; and a light detector that is disposed at a body surface of the patient, and that detects reflected light coming from the scanning position in the imaging subject, at which the illumination light is scanned by the light scanner.
