摘要

提出了一种实现动态目标散射成像的方法。通过四步相移干涉法测量得到光学传输矩阵,数值仿真了相位共轭、Tikhnov正则化和全变分最小化三种重建算法对透过散射介质的不同动态目标的跟踪与重建,并搭建实验装置,验证了此方法的可行性,分析比较了三种算法的重建能力。结果表明,全变分最小化算法的重建效果最好。该方法为生物医学领域中透过散射介质对动态目标成像提供了新思路。

Abstract

Herein, we proposed a dynamic target scattering imaging method. First, we measured the optical transmission matrix by using a four-step phase-shifting interferometry method. Then, we performed numerical simulations of tracking and reconstruction for different dynamic targets through the scattering medium based on phase conjugation, Tikhnov regularization, and total variation minimization algorithms. The feasibility of this method was experimentally verified, and the properties of the three algorithms were compared. The results show that the antinoise ability of the total variation minimization algorithm is the best. The proposed method provides a new idea for dynamic target imaging through scattering media in the biomedical field.
