Dual-function super lens and light rotation detection method

Abstract

The invention discloses a dual-function super lens and a light rotation detection method. The dual-function super lens comprises a super lens body and an end surface connected with the super lens body, wherein the super lens comprises a first dielectric substance microstructure and a second dielectric substance microstructure, the first dielectric substance microstructure is used for carrying out center focusing on emergent light of the end surface, and the second dielectric substance microstructure is used for carrying out off-axis focusing on the emergent light of the end surface. According to the invention, due to the fact that the dual-function super lens can achieve the center focusing function and the off-axis focusing function at the same time, the problem that in the prior art, most super lenses for adjusting the propagation phase adjusting value through dielectric substance microstructures only have the center focusing function, and the function is single can be solved. 本发明公开了一种双功能超透镜和光的旋性探测方法，所述双功能超透镜包括：超透镜镜体和与所述超透镜镜体相连的端面；所述超透镜包含第一介电质微结构和第二介电质微结构，其中，所述第一介电质微结构用于对所述端面的出射光进行中心聚焦，所述第二介电质微结构用于对所述端面的出射光进行离轴聚焦。由于本发明中的双功能超透镜可以同时实现中心聚焦和离轴聚焦两种功能，因此可以解决现有技术中，利用介电质微结构来调节传播相位调节值的超透镜大多只具有中心聚焦的功能，功能较为单一的问题。
