Abstract
本発明は、生体情報を検出するための脈波測定器において、生体の真皮を透過しやすい波長帯の光を検出光として利用することで、皮膚表面付近の圧脈による振動等によるノイズを低減し、例えば耳珠の先端付近であっても脈波測定を可能とすることである。
【解決手段】
第1発明の脈波測定器は、生体に向けて中心波長が0.65μm以上1.85μm以下の光を照射する発光素子と、該発光素子の照射光が前記生体で散乱した散乱光を受光するか或いは前記生体を透過した透過光を受光する受光素子と、を備えることを特徴とする。第2発明の脈波測定器は、生体に向けて発振波長が0.65μm以上1.85μm以下の光を照射するレーザ素子と、該レーザ素子から照射されたレーザ光線が前記生体で反射した反射光と、前記レーザ光線との周波数差を検出する周波数差検出素子と、を備えることを特徴とする。
