T1 - X-ray fluorescence imaging with coded apertures N2 - Our aim is to develop a new method for full field X ray fluorescence imaging at the BAM line @ BESSY II. We will combine an energydispersive array detector for X rays with a coded aperture to get high resolution images . In coded aperture imaging , an object is projected through a mask , producing many overlapping images on the detector . The first part of the project is to perform raytracing simulations to get realistic data and to develop a reconstruction method that allows to get the Information about the investigated object out of the projected image .

A1 - Radtke, Martin T1 - Full field X-ray fluorescence imaging with coded apertures N2 - 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 the information from the recorded image, a reconstruction step is necessary. First tests were carried out at the BAMline at BESSY II. This method enables the simultaneous detection of multiple elements, which is important e.g. in the field of catalysis.
