Abstract: We demonstrate an approach to record spectrally resolved images of x-ray fluorescence emission under full-field illumination with a monochromatic synchrotron beam. We achieve this by combining coded aperture and ghost imaging. Specifically, we record signals of two detection devices: an x-ray camera without energy resolution and a spectrometer without spatial resolution. By joint analysis of these complementary signals, we reconstruct images for each spectral emission line. We compare the performance of this technique with a previously demonstrated computational ghost imaging scheme based on coding only the illumination. Finally, we explore the depth resolution of this approach in view of future single-shot volumetric reconstructions.
