Title: OPTICAL SCANNING ENDOSCOPE APPARATUS
Abstract:
This optical scanning endoscope apparatus is provided with: a light source; an optical fiber (10), which guides illuminating light emitted from the light source, and outputs the illuminating light from the leading end; an optical scanning unit (2) that vibrates, in the diameter direction of the optical fiber (10), the leading end of the optical fiber (10); a return light detection unit (3) that detects light returned from an object (A); an output light quantity detection unit (4) that detects the light quantity of a part of the illuminating light outputted from the leading end of the optical fiber (10); a conversion unit (22) that converts the light quantity detected by the output light quantity detection unit (4) into the whole output light quantity of the illuminating light outputted from the light source; and a control unit (6) that controls, on the basis of the output light quantity thus converted, the light emission quantity of the illuminating light to be emitted from the light source.
