| Abstract: | Abstract The null displacement ring observed in the speckle pattern when a translucent rough surface is rotated is closely related to the conical diffraction phenomena of the gratings. When the mth diffraction order coincides with the null displacement ring, the displacement of this order and the speckle displacement are null. |
