Abstract
【解決手段】検知材料は、入力光と相互作用し、外部の刺激の存在に応じて、入力光のスペクトル分布を非対称に変更するよう構成される。検出器は、変更された入力光を検知し、その入力光のスペクトル分布の中心に対する、変更された入力光のスペクトル分布の中心の移動に関する情報を含む少なくとも1つの電気信号を生成するよう設定される。
【選択図】なし
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。
