摘要
多全息照相实验是大学物理经典综合性实验。利用参物光的干涉条纹记录下物光的振幅、相位及频率,即全部物光信息。学生需完成反射光路的摆放及再现像的观察。实验操作及再现像特点的观察内容复杂而有难度,理论解释难度更大,学生常有疑问。文中针对实验中常需学生观察的正一级虚像的特点(大小畸变、位置和亮度的变化)及原因进行讨论,并作出理论分析。
The optical holograph experiment is a classic and comprehensive one. By recording the interference fringe, we can obtain the information of the amplitude, phase and frequency of the object light, which means the entire information of the object light. The students are required to finish the light path and observation of the imaging. The operation and observation of imaging feature of optical holography is complex and the explain is difficult for students. This article discusses the feature and course of the first virtual imaging. The theoretical analysis would be obtained.
