摘　　要：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.
