Abstract in Portuguese
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.

Abstract in English
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.
