Abstract
【解決手段】観察対象物の吸収波長域の励起光を標本Sの内部に集光させる対物レンズ10と、励起光とは異なる波長の検出光の点光源像を対物レンズ10の瞳9の中心部に結像させて、対物レンズ10により標本Sに検出光を照射させる検出光用光学系27と、対物レンズ10に入射する励起光及び検出光を偏向して標本Sを走査する光走査部5a,5bと、標本Sによる検出光の反射光を検出する光検出部(22〜24,28)とを備える。
【選択図】図1
Description
観察対象物の吸収波長域の励起光を標本内部に集光させる対物レンズと、
前記励起光とは異なる波長の検出光の点光源像を前記対物レンズの瞳中心部に結像させて、前記対物レンズにより前記標本に前記検出光を照射させる検出光用光学系と、
前記対物レンズに入射する前記励起光及び前記検出光を偏向して前記標本を走査する光走査部と、
前記標本による前記検出光の反射光を検出する光検出部と、
を備えることを特徴とするものである。
図1は、本発明の第1実施の形態に係る光音響顕微鏡の要部の構成を模式的に示す図である。本実施の形態に係る光音響顕微鏡は、励起光として、レーザパルス光源1から射出されるパルス光を用いる。励起光は、例えば、標本Sが生体で、生体内の血管をイメージングする場合は、ヘモグロビンの吸収波長域の光が用いられる。なお、観察対象は血管に限定されるものではなく、励起光は観察対象に応じた吸収波長域の光が用いられる。また、標本S内に複数の吸収体が存在する場合は、観察対象の特徴的な吸収スペクトルのピークの波長の光を用いるのが望ましい。レーザパルス光源1からの励起光は、コリメータレンズ2により平行光として射出される。
図2は、本発明の第2実施の形態に係る光音響顕微鏡の要部の構成を模式的に示す図である。本実施の形態に係る光音響顕微鏡は、第1実施の形態に係る光音響顕微鏡と光検出部の構成が異なるものである。すなわち、第1実施の形態では、標本Sにより変調された反射検出光をOCTにより検出したが、本実施の形態では、標本Sにより変調された反射検出光を光ヘテロダイン法により検出する。その他の構成は、第1実施の形態と同様であるので、図1と同様の作用をなす構成要素には同一参照符号を付して説明を省略する。
