Abstract

MéTODO PARA DETERMINAçõ DA QUALIDADE óTICA DE UMA VIDRAçA. Trata-se de um método para determinação da qualidade ótica de uma vidraça, que inclui pelo menos uma área possuindo uma transmissão de luz reduzida, em que é produzida uma imagem de gráfico de sombras da vidraça e a iluminação da vidraça é medida em uma pluralidade de pontos de medição distribuidos em um arranjo que se estende através da vidraça. O desvio de iluminação relativamente a um valor desejado em cada ponto de medição é determinado e na pelo menos uma área de transmissão de luz reduzida a iluminação é omitida do conjunto de pontos de medição.
