Research on infrared polarizing elements and optical systems based on metasurface

Metasurface has the characteristics of small volume and high integration, which can realize the simultaneous regulation of various degrees of freedom such as phase, polarization and amplitude. The dimensional characteristics of its subwavelength structure have become a hot spot in the optical field. Therefore, the combination of the metasurface and the traditional optical system imaging and polarization imaging can obtain the intensity and polarization information of the target, but also ensure the miniaturization and high performance of the new imaging optical system.
