Claims (1)
知器であつて、焦電素子と、この焦電素子を覆う
筒状体と、前面窓にフイルターで素子ブロツクを
形成し、かつ、筒状体の前面を覆うことにより外
乱光の侵入を阻止する断熱材料で形成した遮蔽体
を有するものであつて、この遮蔽体あるいは筒状
体のうち外乱光の被照射部位を鏡面としたことを
特徴とする熱線式検知器。 This is a heat ray detector that mainly detects human bodies etc. using a pyroelectric element, and includes a pyroelectric element, a cylindrical body covering the pyroelectric element, and a filter on the front window to form an element block. A shielding body made of a heat insulating material that covers the front surface of the cylindrical body to prevent disturbance light from entering, and the part of the shielding body or the cylindrical body that is irradiated with the disturbance light is a mirror surface. Features a hot wire detector.
