用可见单色光模拟辐射，提出了一种简单的实验方法来说明射线照相原理。在我们的新方法中，使用平板电脑的液晶显示器作为单色光的光源，作为x射线或中子源的替代品。用彩色打印机在透明的投影仪上打印一个图形（图案）。因此，该方法安全、廉价，而且学生，特别是初高中学生可以通过自己的试错来探索自己的实验。
A simple experimental method for illustrating the principle of radiography has been developed by simulating radiation with visible monochromatic lights. In our new method, an liquid crystal display of a tablet computer was used as a light source for monochromatic lights, which worked as a substitute for an x-ray or neutron source. And a figure (pattern) printed, with a colour printer, on a transparent sheet for an overhead projector was used for the object. Therefore, the method is safe and inexpensive, and has the merit that the students, especially junior/senior high school students, can engage in exploring their experiments through trial and error by themselves.
