Abstract

"MéTODOS E APARELHO USANDO ATENUAçãO DE RADIAçãO PARA DETERMINAR A CONCENTRAçãO DE MATERIAL NO OBJETO". Um aparelho para determinar concentração de dopante em fuligem que constitui pelo menos uma porção de uma pré-forma de fuligem usada para formar uma guia de onda ótica inclui um dispositivo de medição de peso, um dispositivo de medição de parâmetro de espessura, uma fonte de radiação, um sensor de radiação e um dispositivo de determinação. O dispositivo de medição de peso mede o peso da pré-forma de fuligem. O dispositivo de medição de parâmetro de espessura mede um parâmetro de espessura da pré-forma de fuligem. A fonte de radiação irradia a fuligem com radiação de penetração. O sensor de radiação detecta a intensidade de radiação de penetração que passa através da fuligem. O dispositivo de determinação determina uma concentração de dopante na fuligem baseada na intensidade detectada de radiação de penetração e no peso medido e no parâmetro de espessura.
