Abstract

L'INVENTION CONCERNE UN DETECTEUR PYROELECTRIQUE. ELLE SE RAPPORTE A UN DETECTEUR AYANT UN ELEMENT DE MATIERE PYROELECTRIQUE COMPRENANT TROIS REGIONS DELIMITEES, DEUX ACTIVES ET UNE INACTIVE AUX RAYONS INFRAROUGES. LA REGION INACTIVE ET L'UNE DES REGIONS ACTIVES SONT MONTEES EN PARALLELE, ET ELLES SONT MONTEES EN SERIE AVEC L'AUTRE REGION ACTIVE QUI EST POLARISEE EN SENS INVERSE. LES EFFETS AMBIANTS SONT AINSI ANNULES, BIEN QU'IL EXISTE UN CERTAIN DESEQUILIBRE DE DETECTION INFRAROUGE. DES SOURCES ISOLEES DE RAYONS INFRAROUGES PEUVENT AINSI ETRE DETECTEES A DE FAIBLES OU DE GRANDES DISTANCES. APPLICATION AUX APPAREILS D'ALARME CONTRE LES CAMBRIOLAGES.
