In order to study the influence of micropore statistical characteristics of Angel type planar lobster optical devices on the focused imaging performance, a set of point-to-point vacuum X-ray beam test devices was developed in this work. The micro focal spot X-ray beam was used to carry out the focused imaging test on the developed optical device. The knife slit system was used to conduct two-dimensional scanning test on the planar lobster eye optical device. Different degrees of tilt-type process defects were found in different areas of the optical device. The effect of tilt process defects on focused imaging was simulated based on the Monte Carlo software. Experimental results show that the plane lobster eye optical devices used in the experiment can converge the incident X-ray beam into a clear cross image at a focal length of 3650 mm, the maximum full width at half maximum of the focal spot is about 4.63 mm, the corresponding largest angular resolution is about 4.36', and the unevenness of the point spread function is about 33.7%. Simulation results show that tilt-type process defects will decrease the intensity of the central bright spot, the crosshairs are diffuse and discontinuous, the secondary focal spot is distorted, and the image quality is deteriorated.
