Abstract
The effect of surface roughness on the accuracy of displacement determination of an object in digital double exposure technique was studied. From the Young's fringes, it was observed, that the higher the rms of the roughness and the smaller the displacement of the surface the greater is the accuracy of the displacement determination.
