Abstract
【解決手段】光子検知用のセルを複数個含むフォトセンサアレイ42を集積回路内に設け、複数個の経路部分を含む走査経路(y方向)をその上に設定する。アレイ42による光子検知可能波長域即ちサブレンジはy方向位置Y1,Yn,YN毎に異なり、各y方向位置に存するセル群即ちサブレンジセル群は代表波長λ1,λn,λNのサブレンジ内の光子を検知できる。走査器によりアレイ42に対して信号光20を相対走査運動(y方向)させ信号光20によって走査経路沿いにアレイ42の表面を横断走査させると、各y方向位置に位置するサブレンジセル群により対応するサブレンジ内の光子が検知される。信号光20のx方向位置毎の成分即ち場所L1,Lm,LM毎に検知結果を組み合わせ、スペクトラム情報を取得する。
