摘要

结果表明，在以波长数量级的介电微粒子为基础的显微镜下，提供与辐射入射方向成一定角度(与光轴成一定角度)的辐射定位区形成的微粒子可以显著增强空气中的图像对比度。为此，在粒子前面放置一个屏幕，阻挡部分入射光束，形成近场斜照射的光子挂钩或光子射流(terajet)。

Terahertz microscope with oblique subwavelength illumination: design principle

It is shown that the image contrast in the air when using a microscope based on dielectric microparticles with a size of the order of wavelength can be significantly enhanced with the help microparticles that provide the formation of the radiation localisation region at an angle to the direction of radiation incidence (at an angle to the optical axis). For this purpose, a screen is placed in front of the particle, which blocks part of the incident beam, forming a photonic hook or a photonic jet (terajet) with oblique illumination in the near field.
