Abstract

Sistema e método para a inspeção de fissuras internas. É fornecido um método (60) para a inspeção de cavidades internas (44) em uma peça (12). O método (60) inclui inserir (62) uma sonda (14) dentro da cavidade interna (44). O método também inclui controlar (62) a movimentação da sonda (14) utilizando uma trajetória de varredura definida para movimentar a sonda (14) através de uma região de interesse da cavidade interna (44). O método (60) ainda inclui aplicar (64) sinais de excitação com diversas freqUências na sonda (14) de modo a gerar uma quantidade de sinais de respostas multifrequenciais. Os sinais de excitação multifrequenciais são aplicados (68) ao longo da trajetória de varredura definida dentro do cavidade interna (14). O método (60) também inclui realizar uma análise de fase multifrequencial nos sinais de resposta multifrequenciais de modo a inspecionar a cavidade interna (14).
