摘　　要：为了探究光盘(CD或DVD)的光栅衍射规律,以2023年全国大学生物理学术竞赛“色彩线”这一题为例,从理论与实验两方面研究光盘在有无刻录、不同的刻录方式、不同的光路入射角度等条件下衍射条纹颜色的变化情况,探究光盘上光栅衍射规律。结果表明:光盘上衍射条纹颜色与光盘结构、入射光角度和光盘倾角有关。该研究对新型光盘材料和技术的开发有着一定的理论和实践意义。In order to explore the grating diffraction law of optical disc(CD or DVD),taking the“Color Line”of the National Physics Competition for College Students in 2023 as an example,the color change of diffraction fringes of optical disc is studied theoretically and experimentally under the conditions of whether or not the disc is burned,different burning methods and different incident angles of optical path,and the diffraction law of grating on optical disc is explored.The results show that the color of diffraction fringes on the optical disc is related to the structure of the optical disc,the Angle of the incident light and the Angle of the optical disc.The research has a certain theoretical and practical significance for the development of new optical disc materials and technologies.
