Abstract

SE PRESENTA UN APARATO PARA LA DETECCION DE RADIACIONES INFRARROJAS QUE COMPRENDE UN SENSOR PASIVO DE INFRARROJOS (16), UN REFLECTOR DE ENFOQUE (20) CONSTRUIDO Y DISPUESTO PARA ENFOCAR HACIA LA RADIACION INFRARROJA RECIBIDA POR EL APARATO DESDE UNA PRIMERA BANDA DE DISTANCIAS DESDE EL APARATO, Y UN REFRACTOR DE ENFOQUE (14) CONSTRUIDO Y DISPUESTO PARA ENFOCAR LA RADIACION INFRARROJA RECIBIDA POR EL APARATO DESDE UNA SEGUNDA BANDA DE DISTANCIAS DESDE EL APARATO, LA SEGUNDA BANDA DE DISTANCIAS COMPRENDE DISTANCIAS MAS CORTAS QUE LA PRIMERA BANDA DE DISTANCIAS. EL REFRACTOR PUEDE SER UNA LENTE FRESNEL (14) O UNA MATRIZ DE LENTES FRESNEL (32, 33, 34) FORMADAS EN UNA VENTANA DE POLIETILENO (12) A TRAVES DE LA CUAL SE TRANSMITE LA RADIACION. EL REFLECTOR (20) PUEDE SER UN REFLECTOR CONCAVO Y PUEDE INCLUIRSE UN SEGUNDO REFLECTOR PLANO (22) PARA PRODUCIR UNA REFLEXION MAS COMPACTA.
