Fig. 1. Radiography setup with imaging plate, target holder and laser beams. On the right a magnification of the target holder with x-ray source and radiography sample.
Fig. 2. Raw data of the radiography. The projected object is a 400 lpi gold grid. In addition, there are step targets of plastic and aluminum to estimate the dynamic resolution.
