Paper Abstract

A speckle-pattern image method is used to determine the inclination with regard to viewing direction of a diffusing plane surface. We recorded on a photographic plate a defocused double exposure image, illuminating along the viewing direction with two neighbouring wave-lengths. In the experiments we have used, too, diffusing plane dihedrons illuminated in this way. Good agreement with the equation founded is observed.
