In the research of laser inertial confinement fusion (ICF), plasma diagnostics involving X-ray time, space and energy spectrum provides key experimental data for numerical simulation, and effectively promotes the understanding of key physical problems of ICF. The multi-channel grazing-incidence system represented by Kirkpatrick-Baez (KB) microscope is an important means to realize high-resolution X-ray spatial-temporal imaging, which has a wide range of applications in ICF diagnostics research. This paper mainly introduces the development history of high-resolution multi-channel KB imaging system, analyzes the bottleneck problems in the development of KB systems, and focuses on the domestic research progress in the development of multi-channel KB diagnosis system based on multilayer optics in recent years. With breakthroughs in key technologies such as precision thin-film devices and grazing-incidence X-ray optical integration, multi-channel multilayer KB microscope has been widely used in domestic ICF diagnostics, which effectively guarantees the development of relevant physical experiments.
