论文摘要
拉曼散射是一种化学选择性探测机制，在行业和临床环境中具有不同的应用。然而，大多数样品在光学上是不透明的，限制了拉曼探测深度的适用性。在这里，我们通过将有关化学频谱的先验信息与测量频谱分辨的拉曼斑点作为波前形状的反馈机制结合了散射介质后面的化学选择性沉积。我们证明了表演体中前所未有的六倍信号增强，实现了靶向能量沉积，并专注于选定的拉曼活性颗粒。
Raman scattering is a chemically selective probing mechanism with diverse applications in industry and clinical settings. Yet, most samples are optically opaque limiting the applicability of Raman probing at depth. Here, we demonstrate chemically selective energy deposition behind a scattering medium by combining prior information on the chemical's spectrum with the measurement of a spectrally resolved Raman speckle as a feedback mechanism for wavefront shaping. We demonstrate unprecedented six-fold signal enhancement in an epi-geometry, realizing targeted energy deposition and focusing on selected Raman active particles.
