High-resolution imaging diagnosis of X-ray plasma distribution during implosion deceleration phase is urgently needed in inertial confinement fusion experiments. The current curved crystal imaging and the conventional Kirkpatrick-Baez microscope have a spatial resolution of 5 μm, so it is insufficient to obtain the evolution details of implosion target shell and hot spot. In this paper, an aspherical Kirkpatrick-Baez microscope is proposed, to achieve a higher spatial resolution. Simultaneously, an optical design method for aspherical structures is introduced. The imaging system has high reflectivity and good monochromatic performance using periodic multilayer technology. The characterization results show that this imaging system can reach a high spatial resolution of 2 μm in the central field of view.
