Abstract |
|
|
| An analytical formula for the speckle contrast is derived. It represents the dependence of the speckle contrast on the random amplitudes and phases of the interfering scattered waves. It shows also the effect of the number of the scattered waves on the speckle contrast. The normalized speckle contrast considering the randomization of both scattered field amplitudes and phases is slightly different from that of random phases only in the range of low root mean square of phases where the speckle pattern is partially developed. |
