To precisely measure and evaluate X-ray generation and evolution in ahohlraum during an implosion process, we present a two-dimensional (2D) time-and space-resolved diagnostic method by combining a compressed ultrafastphotography (CUP) system and a simplified version of space-resolving fluxdetector (SSRFD). Numerical experiment results showed that the reconstructionquality of the conventional CUP significantly improved owing to the addition ofthe external SSRFD, especially when a coded mask with a large pixel size wasused in the CUP. Further, the performance of the CUP cooperation with the SSRFDwas better than that of adding an external charge-coupled device or streakcamera. Compared with existing ultrafast imaging techniques in laser fusion,the proposed method has a prominent advantage of measuring the 2D evolution ofimplosion by combining high temporal resolution of streak camera and highspatial resolution of SSRFD; moreover, it can provide guidance for designingdiagnostic experiments in laser fusion research.
