Abstract

In this paper, self-modulated ghost imaging (SMGI) in a surrounded scattering medium is proposed. Different from traditional ghost imaging, SMGI can take advantage of the dynamic scattering medium that originally affects the imaging quality and generate pseudo-thermal light through the dynamic scattering of free particles' Brownian motion in the scattering environment for imaging. Theoretical analysis and simulation were used to establish the relationship between imaging quality and particle concentration. An experimental setup was also built to verify the feasibility of the SMGI. Compared with the reconstructed image quality and evaluation indexes of traditional ghost imaging, SMGI has better image quality, which demonstrates a promising future in dynamic high-scattering media such as dense fog and turbid water.

摘要

本文提出了一种在包围散射介质中的自调制鬼成像（SMGI）方法。与传统鬼成像不同，SMGI可以利用原本会影响成像质量的动态散射介质，并通过散射环境中自由粒子布朗运动的动态散射产生赝热光来进行成像。通过理论分析和仿真建立了成像质量与粒子浓度之间的关系。还搭建了实验装置来验证SMGI的可行性。与传统鬼成像的重建图像质量和评价指标相比，SMGI具有更好的图像质量，这表明其在浓雾和浑水等动态高散射介质中具有广阔的应用前景。
