  • Based on the diagnostic requirements of high spatial resolution and high energy spectral resolution in the implosion compression stage of laser inertial confinement fusion (ICF), this paper proposes a large field of view and monochromatic imaging system, which combines KB microscope and diffractive crystal. Under the laboratory condition, the grid is backlight imaged by using the Fe target X-ray tube, with KB microscope and high oriented pyrolytic graphite (HOPG). The imaging results after the crystal energy selection show that the field of view of the system can reach 800 μm, and the resolution of high-resolution area imaging is 37 μm. The detecting results show that the energy resolution of the system is 28, which verifies the monochromatic performance of the system. The system takes into account large field of view, spatial resolution and energy resolution, and has an important application in the research of hot spot structure and mixing effect in the experiment of implosion compression stage.
