Energy-Selective X-Ray Ghost Imaging
Abstract
X-ray ghost imaging (XGI) has opened up a new avenue for damage-free medical imaging. Here energy-selective spectroscopic XGI under poor illumination is demonstrated with a single-pixel detector for the first time. The key device was a specially fabricated Au mask incorporating a new modulation pattern design, by which means images of a real object were obtained with a spatial resolution of 10 μm and a spectral energy resolution of about 1.5 keV. Compressed sensing was also introduced to improve the image quality. Our proof-of-principle experiment extends the methodology of XGI to make possible the retrieval of spectral images with only a single-pixel detector, and paves the way for potential applications in many fields such as biology, material science and environmental sensing. *Supported by the Science Challenge Project (No. TZ2018005), the Civil Space Project (No. D040301-1), the National Natural Science Foundation of China (Nos. 11991073, 11721404, and 61975229), the National Key R&D Program of China (Nos. 2017YFA0403301 and 2018YFB0504302), and the Key Program of CAS (No. XDB17030500).
