Design and fabrication of wider angle field of view hybrid DOEs for a compact imaging optics

Abstract

Hybrid DOEs, which are diffraction pattern arrays fabricated on curved refractive optical elements, have the ability to widen the field of view angle, and improve optical performance and make a compat imaging optics, by combining refraction and diffraction. However, manufacturing a high resolution diffraction pattern array is challenging. We provides a method to manufacture hybrid DOEs with wider field of view and superior performance in both diffraction efficiency and resolution.
