Other AbstractSchmidt and Angel lobster-eye X-ray imaging system can realize total reflection focusing and imaging by simulating lobster-eye microchannel structure. Compared with traditional way of X-ray imaging, it is provided with large field of detection view, high resolution and energy acquisition ability. This paper studies on two lobster-eye basic structures. Based on the principle of grazing incidence, we analyzed Angel and Schmidt structure of light entering focal plane and space resolution. We use tracepro simulation software to model and verify the several focusing and imaging property parameters of these two lobster-eye structures, such as receiving/transmitting light, maximum/cross arm, maximum/background, cross arm/background. The theoretical analysis and simulation results show, when the focal length is longer and channel length-width ratio is about 50. Due to multiple reflection, focusing and imaging signal-to-noise ratio of some main parameters of Schmidt is higher than Angel model, and the spatial resolution is lower. When the focal length is shorter and channel length-width ratio is about 10. Due to simple reflection, focusing and imaging signal-to-noise ratio of some main parameters of Schmidt is lower than Angel model, and the spatial resolution is almost the same.
