Abstract: An optical-scanning observation device including: a laser output unit that outputs a laser beam; a light scanner that radiates the laser beam on an object while scanning; a light detector that detects reflected light of the laser beam; and a controller that sets a detection delay time on the basis of a propagation delay time from when the laser beam is output from the laser output unit to when the reflected light is detected by the light detector and that controls the laser output unit and the light detector such that the light detector detects the reflected light after the detection delay time has elapsed since the laser beam is output from the laser output unit.

Abstract: This method is for calibrating an optical scanning apparatus that includes an optical fiber with a tip supported to allow vibration and an actuator that drives the tip of the optical fiber in a direction perpendicular to the optical axis of the optical fiber. The method includes arranging a position sensitive detector that detects a position of emitted light from the tip of the optical fiber (step S02) and detecting the position of the emitted light with the position sensitive detector while supplying light to the optical fiber and driving the tip of the optical fiber (step S03). The step of detecting (step S03) is performed using an interference fringe reducer that reduces interference fringes occurring along an optical path reaching the position sensitive detector.

Abstract: Color information with higher sensitivity than color information in a primary color system is detected. A laser scanning observation apparatus includes at least three light sources, a multiplexer, and a controller. The at least three light sources emit pulsed laser light with different wavelengths within the visible light spectrum. The multiplexer combines the laser light emitted from the at least three light sources. The controller causes different combinations of two light sources among the at least three light sources to emit laser light in sequence and periodically.
