Description
図1は本発明の双方向起電型光・電流変換装置の一実施形態を模式的に示した図である。図1において、双方向起電型光・電流変換装置本体1は、光透過性を有する電極基板2に導電性薄膜3を備えた電極4と、光透過性を有する電極基板5に導電性薄膜6を備えた対向電極7とを有している。また電極4の表面には、半導体薄膜8を担持し、他方で対向電極7の表面には導電性薄膜9を担持している。さらに2つの電極間には励起電子供与体または正孔供与体物質10と酸化還元物質11とを有している。
図3は本発明の波長情報判別装置の一実施形態の構成を示した図である。本実施形態においては、双方向起電型光・電流変換装置Aの出力が負荷Bに結線され、その両端に発生する起電力を電圧測定器Cにて測定する。その測定電圧値は、信号極性判定装置Dにて判定され、結果は波長の長短表示機Eに表示されるよう構成されている。
図4は本発明の波長情報判別装置の他の一実施形態の構成を示した図である。本実施形態においては、起電方向逆転境界波長がそれぞれλ1およびλ2の双方向起電型光・電流変換装置Aおよびaの出力が、それぞれ負荷Bおよびbに結線され、その両端に発生する起電力が電圧測定器Cおよびcにて測定される。その測定電圧値は、信号極性判定装置Dおよびdにて判定され、結果は波長の長短表示機Eに統合表示されるよう構成されている。境界波長λ1およびλ2に対する波長の長短を判定する対象となる単色光Fは、装置Aおよびaの双方に照射される。
