Claims (1)
- 被検体の検知対象部位に応じて所定の中心周波数に設計されたスプリットリング共振器を有する帯域通過フィルタと、
電磁波を発生させ、前記検知対象部位を前記帯域通過フィルタに近接又は当接させた際の所定の周波数帯域の電磁場応答特性を測定する測定部と、
前記測定部で測定された前記電磁場応答特性の測定値と、生体の電磁場応答特性の基準値と、を用いて評価値を算出する評価値算出部と、
前記評価算出部で算出された前記評価値に基づいて、前記検知対象部位が生体であるか否かを判定する生体判定部と、を備える生体検知装置であって、
前記帯域通過フィルタが、大小2つのスプリットリング共振器が同軸上に内側と外側と、でスプリット部が逆になるように配置された補対型(相補型)スプリットリング共振器を、2組同軸上に、内側に配置された補対型(相補型)スプリットリング共振器の幅、リング長、及びスプリットの幅が、外側に配置された補対型(相補型)スプリットリング共振器の幅、リング長、及びスプリットの幅よりそれぞれ狭くなるように配置した構造を有すること、を特徴とする生体検知装置。
