Abstract
Metalens are composed of designed subwavelength nanostructures at an interface which can control the properties of incident light. Here we demonstrated a GaN metalens array to project a light spots array which can be a light shape generator in the structured light applications. The distance between two light spots is a function with the distance of target. A 10 x 10 achromatic metalens array which arranged by the single metalens diameter is 20 um. The advantages of this metadevice is light weight, small, ultrathin, durable and easy to compact with other device. Our design provides a new avenue for the structure light application such as distance sensing and 3D environmental construction.
