Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Please refer to figure 1 , the present invention provides an anti-temperature interference optical metasurface focusing imaging element, the element includes a silicon dioxide substrate and silicon carbide nanocolumns; the nanocolumns are arranged in a square array on the substrate and rotated at a preset angle for to modulate the phase of the incident light.

[0026] In this embodiment, the two key points for adjusting the phase of the incident light beam are the size of the nanostructure cuboid and the respective rotation angles. According to the desired results, the size of the nanostructure cuboid and each nanostructure can be adjusted accordingly. The angle by which the cuboid is rotated.

[0027] In this embodiment, according to the fact that silicon carbide has high refractive index and light transmittance in the visible light range, and...

Abstract

The invention relates to a temperature-interference-resisting optical metasurface focusing imaging element, which comprises a silicon dioxide substrate and silicon carbide nanorods, wherein the nanorods are sorted in a square array on the substrate, and are rotated by a preset angle to modulate the phase of incident light. The temperature-interference-resisting optical metasurface focusing imagingelement is a metasurface lens composed of the sub-wavelength interval nanostructure cuboid array, is high in integration level, small in size and small in thickness and can be in the micron dimension.

Description

technical field [0001] The invention relates to the field of metasurface focusing imaging elements, in particular to an optical metasurface focusing imaging element resistant to temperature interference and a method thereof. Background technique [0002] Metasurface is a new type of two-dimensional optical material developed in recent years. Its basic unit is composed of sub-wavelength structure, which has ultra-light and ultra-thin properties. A kind of electromagnetic regulation, the metasurface device based on this can easily realize special functions that are difficult or even impossible to achieve with traditional optical devices. Its advantages in resolution and miniaturization are welcomed by market users. While achieving great success, many super-resolution imaging technologies have complex principles, high processing costs, and harsh implementation conditions, which make the system cost high, which greatly limits its practicality.
