Abstract: 1D imaging properties of a reflecting confocal scanning microscope equipped with a superresolving mask are compared to the corresponding free-pupil instrument in the context of subtractive coherent imaging. Enhanced images are obtained that are shown to be not degraded by the losses caused by the filter.
