为了超越“瑞利诅咒”,人们通过将来自点光源的散射光分解成几个空间模式,从而产生了新的超分辨率成像技术,因为耦合到更高阶的模式对横向位移非常敏感。在这里,我们对高数值孔径物镜实现了这样的方法,并证明了对于金纳米粒子,其固有的不对称性导致了耦合到更高阶模而没有横向位移。这种情况不仅适用于实际的纳米粒子,而且由于发射的不对称性,也适用于任何偶极发射体。然而,通过全偏振分析,我们认为可以应用这样的空间模式解复用技术。
The desire to push beyond'Rayleigh's curse'has resulted in new techniques for super resolution imaging by deconstructing scattered light from point sources into several spatial modes, as coupling to higher order modes is exquisitely sensitive to lateral displacement. Here we implement such an approach for high numerical aperture objectives and demonstrate that for gold nanoparticles, their intrinsic asymmetry results in coupling to higher order modes without lateral displacement. This situation not only applies to practical nanoparticles but is applicable to any dipole emitter due to the asymmetry of the emission. However, with full polarization analysis we suggest that one may be able to apply such spatial mode demultiplexing techniques.
