PROBLEM TO BE SOLVED: To provide an optical biological imaging system capable of capturing an accurate and high-definition image of the inside of a living body even when an observation object varies in size and shape.SOLUTION: An optical biological imaging system A comprises: plural proximity detection units 210 arrayed two-dimensionally plural light irradiation units 220 for applying light-source light to an observation object light source units 221 for emitting the light-source light and an imaging unit 100 for imaging light having passed through the observation object. The optical biological imaging system A applies the light-source light from light irradiation units 220 disposed between two or more proximity detection units 210 having detected the proximity of the observation object.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】観察対象の大きさや形状が変化しても、正確かつ高精細な生体内部の画像を取得できる光学的生体イメージングシステムを提供する。【解決手段】二次元配列されている複数個の近接検知部210と、観察対象に光源光を照射する複数個の光照射部220と、光源光を出射する光源部221と、観察対象を透過した光を撮影する撮影部100とを備え、観察対象の近接を検知した2以上の近接検知部210の間に挟まれて配置されている光照射部220から光源光を照射する光学的生体イメージングシステムA。【選択図】図2
