基于矢量空间光调制器的矢量光场通过散射介质的聚焦和成像方法研究

Recently, with increase of successful applications of vector beams in the fields of interaction of light with matter, laser micromachining and superresolution microscopic imaging, charactering and controlling of vectorial optical information have are increasingly becoming a hot research topic of information optics. In this project, we propose a new scheme for research of focusing and imaging of vector beams through disordered or scattering media based on a vector spatial light modulator (VSLM). The main research contents in this project are included: experimentally setup a VSLM system that can quantitatively modulating two-dimensional distribution of the amplitude, phase and polarization parameters of incident beams; study on fast measuring and charactering the vectorial optical information through scattering media; Research vectorial wave front shaping and focusing through scattering media based on the measured vector transmission matrix of the media and the VSLM; research vectorial multifocal multiphoton microscopy, especially based on abruptly autofocusing vector beam array. It hopes, by this project, to further improve the vector beam spatial modulating technique, establish an experimental system for measuring the vector transmission matrix of scattering media and wavefront shaping based on the measurement, and provide a solid experimental basis for measuring and charactering vectorial optical information and related applications.

近年来，随着具有非均匀偏振分布的矢量光束在光与物质相互作用、激光微加工、超分辨显微成像等领域的成功应用，矢量光信息的表征和调控已经成为信息光学的一个新的研究热点。本项目提出了基于矢量空间光调制器（VSLM）的矢量光场通过散射介质的聚焦和成像研究方案，拟开展的研究内容主要包括：建立可以对输出光场的振幅、相位和偏振的二维空间分布进行定量调控的VSLM；研究矢量光场特别是通过散射介质的矢量光信息的快速测量和表征方法；研究基于散射介质的矢量透射矩阵和VSLM的光场通过散射介质的矢量波前整形和聚焦；研究基于矢量多焦点多光子显微成像方法特别是基于矢量突然自聚焦光束及其阵列的显微成像方法。希望通过本项目的研究，进一步完善矢量空间光调制技术，建立基于VSLM的光场通过散射介质的矢量透射矩阵测量和波前整形实验系统，为深入研究矢量光信息的测量、表征及其在显微成像中的应用奠定实验基础。
