我们提出了一种成像技术，允许恢复的深亚波长分辨率的基础上远场强度测量的波长尺度的对象的配置文件。该方法，尺度间混合显微镜（IMM），依赖于衍射元件定位在近场接近的对象，以散射信息携带的倏逝波到传播部分的频谱。结合数值解的麦克斯韦方程组和非线性拟合，然后恢复的信息的基础上的远场强度测量的对象。它表明，IMM有可能恢复波长/20的波长尺度的对象的功能，在存在10%的噪声。(C)2015年美国光学学会
We present an imaging technique that allows the recovery of the profile of wavelength-scale objects with deep subwavelength resolution based on far-field intensity measurements. The approach, interscale mixing microscopy (IMM), relies on diffractive elements positioned in the near-field proximity of an object in order to scatter information carried by evanescent waves into propagating part of the spectrum. A combination of numerical solutions of Maxwell equations and nonlinear fitting is then used to recover the information about the object based on far-field intensity measurements. It is demonstrated that IMM has the potential to recover wavelength/20 features of wavelength-scale objects in the presence of 10% noise. (C) 2015 Optical Society of America
