Abstract: An optical scanning endoscope device includes: a light source that emits illumination light; an optical fiber that emits the illumination light from a distal end; an optical scanner that scans the illumination light on a subject; a return-light detector that detects return light returning from the subject; an emitted-light-amount detector that detects an amount of a portion of the illumination light emitted from the distal end; a converter that converts the detected amount of light into an amount of entire illumination light emitted from the distal end; a controller that controls an amount of the illumination light emitted by the light source based on the converted amount of emitted light; and a calculator that calculates an actual amount of the illumination light based on the detected amount of light and the detected amount of return light. The converter converts the actual amount into the amount of entire emitted illumination light.

Abstract: Provided is a scanning endoscope including: an insertion portion that has a distal-end section and a proximal-end section; a light-guide optical system that guides illumination light toward the distal-end section; a spherical lens that is disposed in the distal-end section and that radiates the illumination light guided by the light-guide optical system onto a subject; an optical waveguide that extends from the distal-end section to the proximal-end section, that receives observation light coming from the subject, and that guides the observation light; and a light detector that detects the observation light guided by the optical waveguide, wherein the optical waveguide is inclined, at the distal-end section, in such a direction as to approach an optical axis of the spherical lens toward a distal end.

Abstract: The optical scanning endoscope apparatus (10) includes: an illumination optical fiber (11) guiding light form lasers (33R, 33G, 33B) and irradiating the light toward an object (100) from an oscillatably-supported tip part of the fiber; an actuator (21) vibratorily driving the tip part of the illumination optical fiber (11); a photodetector (35) detecting light resulting from the object (100) irradiated with the light from the lasers (33R, 33G, 33B) and converting the detected light into an electric signal; a signal processor (37) generating pixel information based on the electric signal output by the photodetector (35); and a light detection controller (31a) controlling a detection property of the photodetector (35) in a period other than an effective detection period.

Abstract: An optical scanning observation apparatus includes a light emission timing controller, a fiber, a driver, a photodetector, an offset processor that corrects an offset value based on an electrical signal output by the photodetector while a light emission timing controller suspends light emission of a light source, and a signal processor that generates an image signal based on the electrical signal for which the offset value was corrected by the offset processor.
