Abstract

Sistema de detección de presencia de objetos compuesto por un dispositivo emisor (1) de radiación electromagnética y un dispositivo receptor (2) de dicha radiación electromagnética donde el dispositivo emisor (1) emite una serie de haces (14) de radiación electromagnética que recorren un plano (3), que se solapan por lo menos parcialmente, y que son emitidos sucesivamente en forma de impulsos, los cuales inciden sobre el dispositivo receptor (2) que envía la información sobre las señales recibidas en un instante dado a una unidad de control, (8) que compara dicha información sobre las señales recibidas en un instante dado con la información sobre las señales recibidas en ausencia de objetos (4) que interfieran con dichos haces (14) de ondas electromagnéticas y analiza dicha comparación para determinar si hay presencia o no de un objeto (4) en dicho plano (3) de detección.
