AI Technical Summary

Technical Problem

Metasurface lenses are less stable and more prone to damage during operation, which affects their reliability.

Method used

The structure is designed with a protective layer, a pattern layer, a filler layer and a support layer. The pattern layer is formed on the protective layer, the filler layer fills the gaps in the pattern layer, and the support layer is connected to the filler layer and/or the pattern layer to form a strong overall structure. The support layer has less influence on the pattern layer.

Benefits of technology

This improves the reliability of the metasurface polarizing beam splitter, making it less susceptible to damage under external impact and internal stress, and enabling it to work reliably.

Abstract

The application discloses a metasurface polarization beam-splitting lens, an environmental sensing device, a vehicle and a manufacturing method of the metasurface polarization beam-splitting lens, and relates to the technical field of optical elements, wherein the metasurface polarization beam-splitting lens comprises a protective layer, a pattern layer, a filling layer and a supporting layer. The pattern layer is formed on one side of the protective layer. The filling layer is arranged on the side of the protective layer facing the pattern layer and fills the gaps in the pattern layer. The supporting layer is arranged on the side of the pattern layer away from the protective layer and is connected with the filling layer and / or the pattern layer. The technical scheme provided by the application can improve the reliability of the metasurface polarization beam-splitting lens.
