Medida de rugosidade por correlação angular de speckle / Measure of roughness by angle speckle correlation

Borbely, Luiz Alberto 18 January 2005 (has links)
Esse trabalho apresenta o método de correlação angular de speckle. Esse método foi melhorado para ser aplicado na medição de rugosidade na faixa de 30 m a 0,1 m. Um programa de computador foi desenvolvido para processar imagens e calcular a correlação angular, e novas fórmulas matemáticas foram deduzidas. / This work presents the speckle pattem angular correlation method. This method was improving to be applicable in the roughness measuring in the range of 0,1 m to 30 m. A software was developed to process image and to calculate the angular correlation, and new mathematical equations were formulating.
