title: Modified Shack-Hartmann sensor made with electrically controlled ferroelectric zone plates.
abstract: A modified Shack-Hartmann wavefront sensor based on an array of electrically controlled zone plates made of ferroelectric domains is presented. The camera used for image acquisition is also used for wavefront sensing. An experimental simulation of the use of this sensor to enhance astronomical images obtained by "Lucky Imaging" is presented.
