Objects that temporally vary slowly may be super resolved using two moving masks such as pinhole or grating. A system of that kind had been previously proposed by Francon and Lukosz. Later on an improvement was obtained by using specially designed Dammann gratings. These approaches require two gratings, one at the object plan and the second at the detectors plane. In this project, the second is replaced by a computer. This way, the synchronization problem existing when two gratings are used in simplified. The method can be applied for both coherent and incoherent illuminations.
