Abstract

Abstract

The core emission was observed by Kirkpatrick-Baez (KB) microscope with about 5 μm space resolution. It is important to evaluate the uncertainty of core image thus to tune the implosion asymmetry. This article evaluates the spatial resolution and SNR of the backlight image got by KB microscope in the experiment, and calculates the uncertainty for the Legendre moments of core emission. The results show that the uncertainty of P₂ is about 6% that of and P₄ is about 8%.
