我们展示了通过混浊层成像，通过使用数字相位共轭的第二谐波场辐射的信标纳米粒子。我们表明，相位共轭焦点可以从它的初始位置，通过照射混浊层的同一区域的角度偏移位移。通过在纳米颗粒周围的区域中通过混浊层扫描相位共轭焦点来获得图像。我们通过测量扫描聚焦光束时透过它的光来获得目标的清晰图像。(C)2010年美国光学学会
We demonstrate imaging through a turbid layer by using digital phase conjugation of the second harmonic field radiated from a beacon nanoparticle. We show that the phase-conjugated focus can be displaced from its initial position by illuminating the same region of the turbid layer with an angular offset. An image is obtained by scanning the phase-conjugated focus through the turbid layer in a region around the nanoparticle. We obtain a clear image of the target by measuring the light transmitted through it when scanning the focused beam. (C) 2010 Optical Society of America
