Abstract

<B>"APARELHO E MéTODO PARA DETECTAR A FASE E AMPLITUDE DE ONDAS ELETROMAGNéTICAS"<D>. A presente invenção se refere a um dispositivo para detectar a fase e amplitude de ondas eletromagnéticas. O dispositivo compreende pelo menos dois portões fotográficos de modulação (1, 2) que são sensíveis à ondas eletromagnéticas. O dispositivo também compreende portões de acumulação (4, 5) que são atribuídos aos ditos portões fotográficos de modulação e que não são fotossensíveis e apresenta conexões elétricas para os portões fotográficos de modulação (1, 2) e para os portões de acumulação (4, 5), de modo que estes últimos possam ser conectados a um dispositivo de saída (de impulsos magnéticos) e o anterior possa ser conectados a um dispositivo de modulação. O dito dispositivo de modulação aumenta e diminui o potencial dos portões fotográficos de modulação (1, 2) relativamente entre si e em relação ao potencial preferencialmente constante dos portões de acumulação (4, 5), correspondentes a uma função de modulação desejada. A invenção fornece uma pluralidade de portões fotográficos de modulação (1, 2) e portões de acumulação (4, 5) na forma de tiras alongadas, estreitas e paralelas, que formam um pixel de PMD em grupos.
