摘　　要：介绍了扫描仪的工作原理和用扫描仪获取低倍照片的操作方法。与用135相机和数码相机获取低倍照片比较,该方法操作更加方便简捷,对实验人员照相技术的要求更低,获取小试样低倍照片更加方便高效,反映材料微细组织结构的能力更强等优点。该方法的缺点是只能拍摄尺寸小于扫描仪面板和表面起伏比较小的试样。The operating principle of a scanner and a new macroscopic photography by scanners were introduced. Compared with traditional method using 135 camera and digital camera, it is much more convenient to operate, much easier to make photos of small samples, and much more efficient to show fine structure. Nevertheless, it could not scan the surface which is fluctuant or larger than the panel.
