基于波前相位动态调控的光学高阶干涉效应及成像的研究

Optical field with particular high-order coherence property is crucial for exploring and studying novel optical high-order interference effects and their applications such as imaging. In this project, we will generate fluctuating light field with particular high-order coherence property via dynamic phase control on coherent light wavefront. With different phase structures loaded on wavefront, optical high-order coherence of the modulated light field will be studied thoroughly by using the free space propagation scheme and other optical schemes, so that active control of optical high-order coherence can be achieved via dynamic phase control on wavefront. Meanwhile, by introducing dynamic phase control on wavefront to control optical high-order coherence, super-resolution imaging based on multi-photon interference will also be explored. This project will extend the basic research on optical high-order coherence, and deepen our understanding of optical high-order coherence, meanwhile, offer new possibilities to explore applications such as imaging based on optical high-order coherence.

具有特定高阶相干特性的光场在探索和研究新颖的光学高阶干涉效应及其在成像等方面的应用中发挥了重要作用。本项目拟通过对光场波前相位进行动态调控，从而产生具有特定高阶相干特性的扰动光场。通过研究波前相位在不同的关联模式下，调制后的扰动光场在自由空间以及其它光学装置中传播时高阶干涉的变化及特点，以实现波前相位动态调控对光学高阶干涉的主动控制。同时，利用波前相位动态调控对光学高阶干涉的控制，构建基于多光子干涉的超分辨成像系统。本项目的展开有助于扩展光学高阶干涉的基础研究，促进人们对光学高阶干涉的认识，并为发展基于光学高阶干涉的成像等应用研究提供了新的途径。
