Equipment for Investigation of Volume Holograms in an Advanced Undergraduate Class on Optics

该提案要求为加州理工学院提供的先进的光学本科实验室提供设备。该设备主要用于教授与体全息术相关的物理学，并向物理和工程专业的学生介绍分层介质这一技术上重要的领域。学生将全息记录光聚合物中的光栅，并将光栅表征为折射率调制，介质厚度，入射角和重放波长的函数。基本的物理概念，如角谱，相位匹配和布拉格散射将被演示，学生将熟悉耦合波理论的概念。

This proposal requests equipment to improve the facilities for an advanced undergraduate laboratory in optics offered at Cal Poly. The equipment is primarily to teach the physics associated with volume holography and introduce physics and engineering students to the technologically important area of layered dielectric media. Students will holographically record gratings in photopolymer and characterize the gratings as a function of index modulation, thickness of medium, angle of incidence and wavelength of replay. Fundamental physical concepts such as the angular spectrum, phase matching and Bragg scattering will be demonstrated and the students will become acquainted with the notions of coupled wave theory.
