X-ray fluorescence imaging with coded apertures
- We developed a new method for full field X-ray fluorescence imaging at the BAMline @ BESSY II. We combined an energy dispersive 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. To get the information about the investigated object out of the projected image, a decoding step is necessary. The first part of our project was to develop the decoding algorithms. We tested the reported reconstruction with an antimask and compared the results with the performance of self-written reconstruction programs based on an iterative and a genetic algorithm. First tests were performed with raytracing simulations. The next step was the collection of experimental data at the BAMline @ BESSY II (HZB). A test objects could be successfully reconstructed with our newly developed algorithm.
