硬X射线相位衬度成像的实验研究
Experimental Research on Hard X-Ray Phase-Contrast Imaging
摘要
介绍了硬X射线(类同轴)相位衬度成像的工作原理及其实验研究结果。X射线波长为0.08860 nm,样品为未经任何处理的飞蛾,记录介质为X射线胶片。胶片经处理以后,用光学显微镜读出,可以看出样品的许多细节,尤其在折射率突变处。而同样条件下基于吸收衬度机制的硬X射线吸收成像,由于是弱吸收样品,没有观察到任何图像。
Abstract
The principle and experimental results of hard X-ray phase-contrast imaging are presented in the paper. The wavelength of the X-ray is 0.08860 nm and the specimen is a natural moth. The obtained image was readout by optical microscope, using Kodak high-resolution X-ray films as recording medium. It is demonstrated that some fine structures of the moth were recognized, especially in the boundary areas of the specimen. Contrarily, no absorption-contrast images were observed under the same conditions.
