PROBLEM TO BE SOLVED: To highly precisely confirm the presence/absence of matters inside an observation object including scattering media such as visceral fat.SOLUTION: This observation device 1 for inside of a scattering medium is provided with a light source 2, an illumination optical system 3 guiding the light L1 from the light source 2 to an observation object A including the scattering media, and an observation optical system 6 acquiring an image of the observation object A illuminated by the illumination optical system 3. Also, the observation optical system 6 is disposed with a light shielding member 8 shielding the image of the light source 2 projected on the surface of the observation object A by the illumination optical system 3 in a position conjugated with the image of the light source 2.COPYRIGHT: (C)2008,JPO&INPIT【課題】内臓脂肪等の散乱媒質を含む観察対象内部の物体の存否を精度よく確認することを可能とする。【解決手段】光源2と、該光源2からの光L1を散乱媒質を含む観察対象Aに導く照明光学系3と、該照明光学系3により照明された観察対象Aの画像を取得する観察光学系6とを備え、該観察光学系6に、照明光学系3により観察対象Aの表面に投影される光源2の像を遮光する遮光部材8が、該光源2の像と略共役な位置に配置されている散乱媒質内観察装置1を提供する。【選択図】 図1
