The application of a Shack-Hartmann sensor with holographic lenslet array to
 the measurements of wavefront aberrations in a speckle field is offered. The main feature
 of the method is that the tested wave front can be compared with an arbitrary wavefront
 preliminary recorded in the holographic memory of the array. An iterative algorithm of
 the sensor work for measuring the variable speckled wavefronts is offered. The
 experimental results of measurements of the curvature of a spherical speckled wave are
 presented. The possibility to use the method proposed in the analysis of deformations of
 a rough surface is shown.
