Description
分析対象が存在しない場合、吸収の中心波長「λcenter,Abs」付近で最大の吸収が発生する。位置検知装置1006が、フォトダイオード部IおよびIIの両方での強度を互いに比較することにより、スペクトル分布の中心を判定する。スペクトル(フォトダイオード部I)の左側でかなり大きな吸収が発生するため、より多くの光量子がフォトダイオード部IIを透過し(したがって、フォトダイオード部IIでより大きな光電流が生成され)、これにより光源の中心波長「λcenter,Lightsource」の右側のどこかに変更された光源のスペクトルの中心が存在し、これがλC1と呼ばれ得る。
検知層に対して特定の分析対象が存在する場合、検知層の吸収が少なくなり、吸収ディップは若干小さくなる。上記の実施例1と比較すると、今度は、より多くの光量子がフォトダイオード部Iを透過し、変更された光源のスペクトルの中心λC2が左側に移動するが、依然として光源のスペクトルの右側の部分に残る。
