摘要:
The purpose of the imaging device according to the present invention is to improve the utilization efficiency of illumination light while being capable of evenly illuminating a wide area. The imaging device is provided with: an imaging optical system (14) having an optical axis (O) and taking images in the peripheral direction with respect to the optical axis and at least one illumination optical system (15) arranged at a position surrounding the optical axis. The illumination optical system (15) is provided with: a reflection surface (23a) for deflecting by reflection a portion of illumination light from the emitting end emitting the illumination light from a light source a refracting surface (24a) for refracting and deflecting another portion of the illumination light and the illumination light reflected by the reflection surface and an emitting surface (24b) for emitting the illumination light refracted by the refracting surface. In a cross section including the optical axis, the reflection surface has a region inclined toward the forward direction approaching the optical axis, the refracting surface having a region inclined toward the direction away from the optical axis is arranged between the reflection surface and the emitting surface, and the emitting end is arranged in a radial direction position between the rear end of the refracting surface and the rear end of the reflection surface.Linvention concerne un dispositif dimagerie visant à améliorer lefficacité dutilisation de la lumière déclairage tout en étant capable déclairer de manière uniforme une large zone. Le dispositif dimagerie comporte : un système optique dimagerie (14) ayant un axe optique (O) et prenant des images dans la direction périphérique par rapport à laxe optique et au moins un système optique déclairage (15) situé au niveau dune position entourant laxe optique. Le système optique déclairage (15) comporte : une surface de réflexion (23a) pour dévier par réflexion une partie de la lumièr
