摘要

隨著iPhone SE2仍大力採用結構光3D感測，顯見光學繞射元件（Diffractive Optical Elements, DOE）仍有一定重要性，除此之外，DOE結構應用包括用於擴增實境、混合實境、虛擬實境（AR／MR／VR）元件的波導管，以及在車用、消費性電子和商業應用中的先進光學感測元件等。因此如何快速和低成本的製造DOE，已是業界相當關注的事，過去UV型的微結構快速製造技術（奈米壓印）在微奈米結構快速成型上和低成本製造上已經有很好的發展，此次隨著DOE發展再度被關注，本文將介紹結構光學的產業趨勢，並介紹UV型的微結構快速製造技術在DOE應用發展，提供下一世代光學元件和其終端產品提供可用於量產的技術建議。

As iPhone SE2 continues to adopt structural optical 3D sensing technology, it is clear that Diffractive Optical Elements (DOE) are very important. The DOE applications include waveguide for Augmented Reality, Mixed Reality, Virtual reality (AR/MR/VR) components, and advanced optical sensing components for vehicle, consumer electronics, and commercial applications. Therefore, how to produce DOE effectively with low-cost has attracted attention in the industry. In the past, UV-type microstructure rapid manufacturing technology (Nanoimprint Technology) has been well established in micro-nanostructure rapid molding and low-cost manufacturing. Based on this solid foundation, the nanoimprint technology now attracts attention again with the development trend in DOE. This article will introduce the industrial trend in structural optics and also introduce the development of UV-type microstructure rapid manufacturing technology in DOE application, to provide the insight and advices for mass producing next generation optical components and its end products.
