光路中的强散射可以被主动利用来确定光传播和通过混浊介质的聚焦，并最终提高光学成像和光操纵能力。光整形器与强散射结构一起的使用使得能够产生被限制在纳米级中的焦点，或者另一方面可以提供显著增强的视场。利用这一概念，我们引入了专门的工程散射结构，通过直接飞秒激光写入在玻璃块中，呈现一维各向同性，并与精确相位成形的照明光一起，我们在用户定义的位置产生亚微米薄光片。我们的方法允许我们将不同波长的光聚焦到相同的定义位置，而无需移动任何光学元件和校正色差。此外，我们证明，在一维呈现各向同性的天然生物组织也可以用于直接在生物样品中产生光片。(C)2016美国光学学会
Strong scattering in the optical paths can be proactively exploited for determining light propagation and focusing through turbid media and ultimately improve optical imaging and light manipulation capabilities. The use of light shapers together with strongly scattering structures enables the production of foci confined in the nanoscale or on the other hand may provide significantly enhanced fields of view. Exploiting this concept, we introduce ad hoc engineered scattering structures, by direct femtosecond laser writing in the bulk of glasses, presenting isotropy in one dimension, and together with precisely phase- shaped illuminating light we produce submicrometer thin light sheets at user- defined positions. Our approach permits us to focus light of different wavelengths onto the same defined position without moving any optical element and correcting for chromatic aberrations. Furthermore, we demonstrate that natural biological tissues presenting isotropy in one dimension can also be used for generating light sheets directly in the biological sample.
