Abstract

Patente de Invenção para <B>"DISPOSITIVO óTICO DE MEDIDA à DISTâNCIA, SEM CONTATO DE UMA FONTE LUMINOSA"<D>. Dispositivo de medida à distância sem contato de uma fonte luminosa, comportando um meio de detecção ótica formado de detetores elementares e um conjunto de N meios de imagem, sendo que os meios de imagem permitem a imagem da fonte luminosa sobre um plano na vizinhança daquele meio de detecção, formando, deste modo, sobre o dito meio, um conjunto de pelo menos três manchas luminosas, cada mancha se espalhando sobre pelo menos dois detetores elementares; dispositivos comportando além do mais, um circuito de cálculo permitindo, a partir das posições relativas de pelo menos três manchas luminosas, calcular pelo menos um parâmetro característico da distância da fonte luminosa do dispositivo com uma precisão dependendo do número N de manchas luminosas.
