A stereo imaging system based on synchrotron radiation X-rays is built in the BL13W beam line of the Shanghai Synchrotron Radiation Facility. The system uses two bending capillary tubes to extract synchrotron radiation photons and divides them into two intersected beams. The experimental sample is placed at the intersection of two X-ray beams and two projections of the sample are recorded simultaneously by a detector placed close to the sample. The depth information of each element of the sample is calculated by parallax equations and relevant algorithms, and the pseudo three-dimensional image of the sample is produced. Compared with X-ray computed tomography, the proposed method improves the time resolution notably, which is even close to the duration of a single exposure. It can be used for real-time imaging and reduce the radiation dose of the sample. A numerical simulation is performed with the projection of blood capillary in the mouse liver and achieves an ideal result. A spiral wire model is then taken as a sample to conduct stereo imaging in the experimental platform. The preliminary experimental result demonstrates that the stereo information of the spiral wire can be recognized clearly.
