Curved crystal X-ray imaging system is developed for large laser facility in LFRC, and high spatial resolution, high energy resolution and wide field monochromatic X-ray image is obtained. The highest spatial resolution up to 6 microns and magnification 12X of four period grid image, by using 5 lasers focusing on vanadium foil and 5.205keV monochromatic X-ray backlit and monochromatic imaging by curved crystal. Using X-ray streak camera for recording system, the implosion trajectory precision measurement obtained. And this imaging system is used in laser-driven reshock experiment and RT instability experiment, and wide field view and high quality images of examples turbulence at different times are obtained. Experiment results show that the curved crystal imaging system is one of important X-ray diagnostic methods in implosion and RT experiments.
