中文摘要:改进的衍射超分辨率元件(DSE)被应用于提高双光子三维(3D)微加工系统中的微加工径向超分辨率,该系统仅在几年前出现,并且可以提供将光化学和物理反应限制在三维激光波长范围内的能力。改进的DSE的设计方法是,在设定M的最高极限M u和G的最高极限G u的情况下,使S最大化,其中参考文献[1]解释了S、M和G的定义。模拟结果表明,通过改进的光学DSE可以获得微加工径向超分辨率。这种现象只能解释为高阶和零阶衍射峰的侧面在双光子吸收(TPA)聚合阈值下被拍打。总之,聚合体积可以选择,因为M u和G u是相应可调的,即使激光波长、物镜和光敏树脂对于给定的微加工系统是固定的。这意味着可以选择双光子微加工的径向超分辨率。

英文摘要:The improved diffractive superresolution element (DSE) is being applied to improve the microfabrication radial superresolution in the two-photon three dimension (3D) microfabrication system, which appeared only a few years ago and can provide the ability to confine photochemical and physical reactions to the order of laser wavelength in three dimensions. The design method of the improved DSE is that maximizing S if the highest limit M u of the M and the highest limit G u of the G is set, where reference [1] explained the definition of the S, M and G. Simulation result proved that the microfabrication radial superresolution can be got by the improved optical DSE. The phenomenon can only be interpreted as the intensity of high-order and side of the zero-order diffraction peaks have been clapped under the two-photon absorption (TPA) polymerization threshold. In a word the polymerized volume can be chosen because the M u and the G u is correspondingly adjustable, even if the laser wavelength, objective lens and the photosensitive resin is fixed for a given microfabrication system. That means the radial superresolution of the two-photon microfabrication can be chosen.
