摘要
白炽灯光入射在CD/DVD光盘会呈现随着角度轻微变化发生相应变化的彩色线.基于CD/DVD光盘的制造工艺,利用MATLAB软件对衍射规律进行理论分析,使用分光计实验观察白炽灯照射下CD/DVD光盘呈现出彩色线的衍射现象,验证不同入射角、衍射角、水平偏转角与波长的关系,获得不同条件下的衍射图案.为光学和材料科学等多个学科领域以及数字储存技术的发展提供新的思路和方向.
Abstract
An incandescent light incident on a CD/DVD disc presents colored lines that change with slight changes in angle.Based on the manufacturing process of CD/DVD disc,the diffraction law was theoretically analyzed by using MATLAB software,and the diffraction phenomenon of color lines on CD/DVD disc under the irradiation of incandescent lamp was observed by spectrometer experiment.The relationship between incidence angles,diffraction angles,horizontal deflection angles and wavelength was verified,and diffraction patterns under different conditions were obtained.It provides new ideas and directions for the development of many subject areas such as optics and materials science as well as digital storage technology.
