外文摘要：The diffractive optical element[DOE]is an important component of three-dimensional[3D]imaging systems based on struc-tured light.In this work,we designed the metasurface-driven D0Es based on generalized Rayleigh-Sommerfeld diffraction theory to project large field of view[FOV]pseudo-random dot array for 3D imaging.We measured an efficiency of 61.04％and root-mean-square error[RMSE]of 0.45 for the 60° FOV sample and an efficiency of 42.96％and RMSE of 0.75 for the 144° FOV sample.Because the pattern is designed based on the generalized Rayleigh-Sommerfeld diffraction theory,the projected pattern is similar to the target pattern and has even intensity.
