Abstract

Dispositivo para determinar un cierto plano ópticamente y de preferencia visualmente, construido de manera que, mirando el dispositivo se obtiene información sobre si el observador o el objeto se encuentran en uno u otro lado de dicho plano o si están en dicho plano y que comprende dos o más unidades de pantalla, caracterizado porque está provisto de por lo menos un sistema de pantallas reticuladas, que comprende una primera pantalla delantera (2) que forma un ángulo con una pantalla posterior (1) situada detrás de dicha primera pantalla delantera (2), y porque la primer pantalla delantera (2) tiene una retícula que es distinta de la retícula de la pantalla posterior (1), con lo que, cuando pasa luz a través de las pantallas (1,2) se producen imágenes de interferencia denominadas diagramas de muaré.
