At the SILEX-Ⅰlaser facility penumbral imaging technique was used to record a Kα source in two dimensions. Due to the fact that the source was produced via the interaction between ultrashort-ultraintensity laser and ‘Velvet’ target we can obtain high quality Kα source images. More details about the source spatial distributions can be deduced from the two-dimensional imaging than that from the one-dimensional imaging such as knife edge imaging.
