The paper reports on a new class of instruments that promises to bring high efficiency also to X-ray polarimetry, the last unexplored field of X-ray astronomy. It will then be possible to resolve the internal structures of compact sources which otherwise would remain inaccessible, even to X-ray interferometry. These instruments derives the polarization information from the track of the photoelectrons imaged by a finely subdivided gas detector. Its great improvement of sensitivity (at least one order of magnitude) will allow the direct exploration of the most dramatic objects of the X-ray sky.
