Claims (1)
る方向の赤外線を各凹面鏡のほぼ共通した焦点位置に置
かれたデュアル形式の赤外線検知器で検知する装置にお
いて、特定方向に対応する凹面鏡を２分割して、それぞ
れの凹面鏡を前記赤外線検知器の有効検知角度の外側に
配置するとともに両者で一対の感熱帯を構成するように
したことを特徴とする受動型赤外線検知装置。In a device in which a plurality of concave mirrors with different viewing directions are provided and infrared rays in a direction corresponding to each concave mirror are detected by a dual-type infrared detector placed at a substantially common focal position of each concave mirror, two concave mirrors corresponding to a specific direction are detected. A passive infrared detection device characterized in that the concave mirrors are divided and each concave mirror is placed outside the effective detection angle of the infrared detector, and both constitute a pair of sensitive areas.
