摘要： An endoscope light source device includes a light source to emit light, and a speckle reduction member to scatter the light. The reduction member has a surface including thickness variation to provide the light with an optical path difference. The device also includes a drive to move the reduction member, and a lens to condense the light passed through the reduction member onto a light guide of an endoscope. The surface of the reduction member has inclination of an average inclination angle. The average inclination angle is determined so that a light quantity loss rate of the entering light into the light guide by scattering of the reduction member and refraction of the lens has a positive value equal to or smaller than an effective allowable loss rate.

摘要： An insertion module inserted into inside of an observed object includes a light-source light emitting module, around its distal end, configured to emitted light from a light source and a detector, provided close to the distal end, configured to detect a light quantity of incident visible light. A controller controls the light source such that a null signal is transmitted from the light-source light emitting module, the null signal being characteristic for detection of the position of the distal end and obtained by making at least light of a predetermined wavelength region have an absence of visible light. The detector performs detecting operation in a period in which the null signal is transmitted. A determination module performs determination relating to the position of the distal end, based on detection information outputted by the detector.
