摘　　要：The measurement of X-ray continuous emission from laser-driven plasma was achieved through multiple monochromatic imaging utilizing a multilayer mirror array.This methodology was exemplified by the development of an eight-channel X-ray imaging system,capable of operating in the energy range of several ke V with a spatial resolution of approximately3 μm.By integrating this system with a streak camera,the temperature and trajectory of imploding capsules were successfully measured at the kJ-class Shenguang III prototype laser facility.This approach provides a synchronous diagnostic method for the spatial,temporal and spectral analysis of laser-driven plasma,characterized by its high efficiency and resolution.
