Abstract

Un sensor capaz de detectar materiales transparentes u opacos. El sensor puede estar dispuesto alrededor de un tubo transparente que transporta un materialcomo un líquido. El sensor utiliza una fuente luminosa de haces finos y un fotodetector de área extendida. Un comprador de ventanas determina la presencia oausencia de un material como un líquido.
