摘要

在為(wèi)增強和(hé)混合現實(AR&MR)應用設計(jì)光導設備的過程中,像提供的視(shì)場(chǎng)(FOV)這樣的參數(shù)是主要的關注點。為(wèi)了提高(gāo)可(kě)達到的最大(dà)視(shì)場(chǎng)的極限,已經研究了各種方法,例如在耦入器(qì)到耦出器(qì)之間(jiān)傳播過程中分離視(shì)場(chǎng)的系統。一種非常流行(xíng)的方法是所謂的“蝴蝶光瞳擴展”,即兩個(gè)單獨的EPE光栅區(qū)域用于視(shì)場(chǎng)的正負部分,這也應用于微軟的Hololens 2。在本文檔中,我們展示了基于微軟US9791703B1專利的VirtualLab Fusion中這樣一個(gè)EPE概念的實現。
