Abstract
An endoscope system has observation modes making observations with lights having optical characteristics different from each other. The system includes an endoscope including an insertion section provided with an illumination window, a light guide arranged in the insertion section, and including an entrance end on which the lights enter and a plurality of light guide areas that guide the lights entered on the entrance end, and an entrance area switching unit that switches between the light guide areas through which the entered lights are guided by switching between areas on which the lights enter at the entrance end in accordance with an observation mode.
Claims26
An endoscope system having a plurality of observation modes making observations with lights having optical characteristics different from each other, the endoscope system comprising:
- an endoscope including an insertion section provided with an illumination window, the endoscope having a light guide arranged in the insertion section, the light guide including an entrance end on which the lights enter, the light guide including a plurality of light guide areas for guiding the lights entered on the entrance end;
- and
- an entrance area switching unit that switches between the plurality of light guide areas through which the entered lights are guided by switching between areas on which the lights enter at the entrance end of the light guide in accordance with one of the plurality of observation modes,
- wherein the lights have coherence;
- and
- the plurality of observation modes include a speckle observation mode in which a speckle caused by the lights in the observation object is observed.
