Abstract

La presente invención se refiere a en un dispositivo de detección infrarroja de intrusiones, que tiene un primer campo de visión que incluye una primera trayectoria óptica que cuenta con un arreglo de lentes fresnel dispuesto frente al sensor de radiación infrarroja, para dirigir la radiación incidente directamente sobre el sensor, la mejora que comprende: un alojamiento que circunda una porción de la primera trayectoria óptica, esta porción incluye el arreglo de lentes y el sensor; el alojamiento tiene una primera y segunda aberturas, con la primera abertura dispuesta para suministrar el primer campo de visión y la segunda abertura dispuesta para suministrar un segundo campo de visión, cuando menos desplazado por noventa grados del primer campo de visión, la abertura permite que la radiación infrarroja incidente sea recibida del segundo campo de visión para entrar en el alojamiento a lo largo de una segunda trayectoria óptica; y un elemento óptico, dispuesto en el alojamiento a lo largo de la segunda trayectoria óptica, este elemento óptico dirige la radiación infrarroja incidente recibida desde el segundo campo de visión al sensor.
