Abstract |
|
|
| Analytical formula for the autocorrelation speckle intensity is derived. The derivation based on the autocorrelation function of the speckle field of non-circular statistics. The autocorrelation function shows its dependence on the lateral correlation length of the roughness, the root mean square of the random roughness heights and also its dependence on the speckles lateral displacement. Experimental validations are carried out through the visibility of interference pattern obtained through mixing two lateral separated speckle patterns. It is investigated for different average roughness heights and for different speckle lateral displacements. |
