Description

一种基于介质微球的微米聚焦虹的产生方法及光谱仪A method and spectrometer for generating micro-focusing rainbow based on dielectric microspheres 技术领域technical field
本发明涉及光学色散技术领域，具体涉及一种基于介质微球的微米聚焦虹的产生方法及光谱仪。The invention relates to the technical field of optical dispersion, in particular to a method and a spectrometer for generating a micro-focusing rainbow based on medium microspheres.
背景技术Background technique
彩虹，又称天虹，是自然界中的光学现象。1666年，牛顿利用三棱镜对太阳光进行分解，获得了像彩虹一样的七色光。随后，关于彩虹的光学原理被逐渐完善。三棱镜分解太阳光这种现象被称为色散，目前光的色散可以用三棱镜、衍射光栅和干涉仪等来实现，这三种色散器件可以作为光谱仪的色散系统。然而这些光学元件产生的色散不能聚焦，需要另加聚焦系统。另外，这些器件结构尺寸大，限制了光谱仪的小型化。Rainbows, also known as rainbows, are optical phenomena in nature. In 1666, Newton used a prism to decompose sunlight and obtained seven colors of light like a rainbow. Subsequently, the optical principle of the rainbow was gradually perfected. The phenomenon of decomposing sunlight by a prism is called dispersion. At present, the dispersion of light can be realized by a prism, a diffraction grating and an interferometer. These three dispersive devices can be used as the dispersion system of the spectrometer. However, the dispersion produced by these optical elements cannot be focused, requiring an additional focusing system. In addition, the large size of these device structures limits the miniaturization of spectrometers.
球透镜对光具有汇聚作用。近些年，人们发现微球介质透镜能够产生高强度、窄光束的聚焦。利用这些性质，发现介质微球具有超分辨成像的能力。人们对介质微球聚焦特性进行了大量研究，并没有发现其色散能力。The ball lens has a converging effect on light. In recent years, microsphere dielectric lenses have been found to produce high-intensity, narrow beam focusing. Taking advantage of these properties, the medium microspheres were found to have the capability of super-resolution imaging. A lot of research has been done on the focusing properties of dielectric microspheres, but their dispersion ability has not been found.
