s代表平面光学表面的宽度,b代表eyebox,r代表出瞳距离,而v代表FOV 。s=b+2 r tan(v/2) “这些关键指标相互联系和相互制约,提高一项将意味着牺牲另一项,比如在提高FOV的同时,就容易造成更大的光机体积和更小的eyebox。而小型光学模组若想实现大FOV、大eyebox则极具挑战,而且大eyebox需要更多光线才能实现自然的...
目前市场上的AR光学模组与人眼视场角相比，仍有较大差距，而VR头显的FOV则因更简单的光学配置而相对较大。然而，要达到如DigiLens声称的150°对角线FOV，技术上需要解决光学模组尺寸过大、双目重叠等问题，这还处于探索阶段。Eyebox的尺寸至关重要，至少要与瞳孔相当，且考虑到IPD调节需求，它需要适度扩展...
