光的超声波标记提供了一种探测混浊介质内光子密度的独特方法。我们证明，这种技术允许人们以非侵入方式探测众所周知的香蕉形光子密度，从而产生了一种用于模拟扩散光子传播的新工具。此外，我们表明这种技术是定量的，可以精确测定混浊介质内的吸收成分。
Ultrasound tagging of light provides a unique way to probe photon density inside turbid media. We show that this technique allows one to probe the well-known banana-shaped photon density noninvasively, giving rise to a new tool for modeling diffusive photon propagation. Moreover, we show that this technique is quantitative and allows one to get a precise determination of the absorbing constituents inside the turbid medium.
