Abstract

We introduce and experimentally demonstrate acousto-optic-assisted diffuse optical tomography (DOT) using a holography-based acousto-optic setup. The method is based on probing a scattering medium with a localized acoustical modulation of the phase of the scattered light. The optical properties of the scattering medium are recovered with ultrasound-limited resolution by applying DOT reconstruction methods on a set of the measured intensities of light, modulated at different locations throughout the medium.

摘要

我们介绍并实验证明了一种基于全息术的声光辅助漫射光学层析成像（DOT）方法。该方法基于用散射光的相位局部声学调制来探测散射介质。通过在整个介质的不同位置处调制的一组测量光强度上应用 DOT 重建方法，可以以超声限制的分辨率恢复散射介质的光学性质。
