Profile measurement of the fabricated 255 levels grayscale lens ( f = 100mm) on Zygo profilometer (NewView 7300). (a) The grayscale Fresnel lens on AZ4562 photoresist. (b) the lens transferred to UV resin by UV imprint

Abstract

Grayscale Diffractive Optical Elements (DOEs) offer superior versatility and precision in shaping light fields compared to multi-level D OEs. Its continuous grayscale modulation enables finer control, leading to enhanced performance in various optical applications..
