Abstract
"REFRATÈMETRO COM GRADEAMENTO DE BRAGG ABRASADO". Para medir o índice refrativo de um meio (18), por exemplo, um líquido ou gás, esse sistema compreende uma guia de onda (14)tendo um gradeamento de bragg abrasado (16), a resposta espectral do qual depende do índice refrativo do meio, uma fonte de luz (20)para fazer essa luz interagir com o gradeamento, meios (22)para a análise espectral da luz que interagiu com o gradeamento, meios (24)para recuperar o espectro provido pelo meio de análise espectral e meios (26)e meios (26) para correlacionar, do espectro recuperado, a resposta espectral do gradeamento com um valor do índice refrativo do meio.
