Our aim is to develop a new simple and inexpensive method for full field X-ray fluorescence imaging . We combine an energy dispersive array detector with a coded aperture to obtain high resolution images . To obtain the information from the recorded image a reconstruction step is necessary . The reconstruction methods we have developed , were tested on simulated data and then applied to experimental data . The first tests were carried out at the BAM line @ BESSY II. This method enables the simultaneous detection of multiple elements , which is important e.g. in the field of catalysis.
