Abstract
Imaging through a dynamical scattering medium is a difficult task, where strong multiple light scattering from flowing scatters dynamically destroys imaging formations. Coherent detecting is a promising method to solve above problem. Here we experimentally investigate a non-invasive coherent detecting scheme based on two-photon absorption capable of imaging through rotating diffuser. In order to demonstrate our method, we also accomplish one-photon coherent imaging. The experimental results show that two-photon imaging is able to resist the dynamical scattering medium. This technique combined with highly sensitive detectors may pave a new way for imaging through fog, turbid sea, and rain as well as biomedical imaging applications.
