Abstract
【解決手段】透明ガラス基板24の背面に高屈折率材料膜28と低屈折率材料膜30の積層膜からなる反射膜26を形成してミラー素子14を構成する。ミラー素子14の可視域での積分球反射率は40〜60%、近赤外域での透過率は近赤外カメラ16の全感度波長域のうち近赤外域に属する一部または全部の帯域で70%以上である。反射膜26の背面全体に黒色マスク部材18を装着する。黒色マスク部材18の背後に近赤外カメラ16を配置する。黒色マスク部材18の全領域のうち近赤外カメラ16の撮像範囲に該当する領域は可視光吸収・近赤外透過フィルター18aで構成する。可視光吸収・近赤外透過フィルター18aの近赤外域での透過率は近赤外カメラ16の全感度波長域のうち近赤外域に属する一部または全部の帯域で70%以上である。
