Abstract
MÉTODO E DISPOSITIVO PARA ANÁLISE DE PROPRIEDADES VISUAIS DE UMA SUPERFÍCIE. A presente invenção refere-se a um método para imagem de uma amostra por meio de um dispositivo tendo uma cavidade com paredes internas e uma abertura de amostra, o dispositivo ainda compreendendo um meio de iluminação para a iluminação da cavidade e um dispositivo de formação de imagem digital direcionado da cavidade para a abertura de amostra, o método compreendendo as seguintes etapas: - apresentar uma amostra á cavidade por meio de uma abertura de amostra; - iluminar a cavidade; - ativar o dispositivo de formação de imagem para registrar uma imagem da amostra; - comunicar os dados de imagem registrada a uma unidade de processamento de dados programada com software de análise de imagem para analisar a imagem registrada, caracterizado pelo fato de que a parede interna da cavidade absorve luz e pelo fato de que pelo menos uma parte do meio de iluminação é formada pelas fontes de ponto de luz uniformemente distribuídas sobre pelo menos uma parte da parede interna da cavidade, e uma seleção das fontes de ponto de luz é ativada dependente do grau desejado de direcionalidade de luz.
