摘要

利用北京同步辐射光源研究了准平行束X射线同轴轮廓成像中影响成像质量的若干因素。结果表明

同步辐射光束在垂直方向能获得更好的边缘增强效果。尺寸较大的样品能获得更高的衬度。随着样品到探测器距离的增大

衬度增大

但存在一个最佳距离。高分辨率的探测器可以获得较高的衬度和较好的边界锐度。

Abstract

Factors that affect the image quality of in-line outline X-ray imaging are investigated with 4W1A light source in Beijing Synchrotron Radiation Facility (BSRF). The experimental results show that better edge-enhancing effect can be achieved in vertical direction of the synchrotron radiation beam. Higher contrast can be obtained for larger size samples. The image contrast increases with the sample-detector distance (SDD)

and there is an optimal distance. The influence of detector resolution is also investigated

the better contrast and higher edge-sharpness can be achieved for the detectors with higher spatial resolution.
