Using the linear canonical transform and ABCD ray matrix techniques to describe these general optical systems, we ﬁrst derive analytical formulas for determining axial and lateral speckle sizes. Then using a numerical technique, we extend the analysis so that the correlation properties of nonaxial speckles can also be considered. Using some simple optical systems as examples, we demonstrate how this approach may be conveniently applied. The results of this analysis apply broadly both to the design of metrology systems and to speckle control schemes||Funding Details:||Science Foundation Ireland
