Developed a set of two-dimensional position sensitive detector based on micro-channel plate (MCP) and conducted a series of X-ray imaging tests. Image of Vernier-caliper proves our equipment has an edge resolution of about 500 μm. Imaging tests were carried out on the composite samples. When the X-ray machine's target flow was 1 mA, the clear imaging could be realized within 1 ms. Image rebuilding has also been adapted afterwards, median filtering combined with sharpen, blind deconvolution and Wiener filtering have been used respectively to reconstruct the original image of Vernier caliper. All of the three methods have a positive effect on image's quality but wiener filtering becomes the optimal method among those three which improves the edge resolution by 7%.
