Abstract
【解決手段】光(290)を光センサ(205)に方向付けし、方向付けられた光から赤外線成分をフィルタリングして除去するための方法と装置。この装置(200)は、基板(204)上に配置された光センサ(205)のアレイを含み、光センサは、光の強度を電圧信号に変換するように動作可能である。装置(200)は、光センサ上に配置されたカバープレート(230)を更に含み、そのためカバープレートは光センサアレイ上にキャビティ(221)を形成する。装置(200)は、光センサ(205)とカバープレート(230)との間に形成されたキャビティ内において、カバープレートと光センサとの間に配置されたフィルタ材料を更に含む。このフィルタ材料は、カバープレートを通過する光をフィルタリングするように動作でき、特に、赤外範囲の波長を有する光がフィルタリングされて除去され得る。
