Abstract: A connection adapter includes: an adapter housing; a split sleeve; and a spacer having a space determiner disposed inside the split sleeve and an angle determiner that passes through the slit of the split sleeve to be secured relative to the adapter housing. The two connector connection pars are each connected to the connectors, respectively, causing the ferrules of the connectors to be fitted into the split sleeve and secured across the spacer, so that the single mode optical fibers of the connectors are optically connected to each other via no point of contact therebetween, to thereby provide a connection adapter capable of creating stable connection efficiency for optical fibers and an endoscope device using the connection adapter.

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 temperature measurement method for measuring an ambient temperature of a long-length medical device, using first and second optical fibers attached to the medical device, the first and second optical fibers extending in parallel with each other along a longitudinal direction of the medical device, and the first optical fiber having a distal end serving as a measurement unit extending beyond a distal end of the second optical fiber along a longitudinal direction of the first and second optical fibers. The method includes: measuring an optical path length difference between a first optical path including the first optical fiber and a second optical path including the second optical fiber; and calculating a temperature of the measurement unit based on the optical path length difference. When temperatures of the first and second optical fibers are uniform, optical path lengths of the first and second optical paths are equal.

Abstract: An apparatus for measuring a scanning pattern of an optical scanning apparatus can easily reduce the effect of stray light and improve the measurement accuracy of the scanning pattern. An apparatus for measuring a scanning pattern of an optical scanning apparatus (100), which scans an object being illuminated with illumination light and generates a display image of the object being illuminated, includes a screen (11) scanned by the illumination light and an optical position detector (12) that detects the position of an irradiation spot of the illumination light on the screen (11). The apparatus for measuring a scanning pattern sequentially detects a position of the irradiation spot at predetermined time points with the optical position detector (12) during scanning of the screen (11) to measure the scanning pattern of the illumination light.
