虛擬現(xiàn)實(shí)眼鏡光學(xué)組件的設(shè)計(jì)與分析
摘要：針對(duì)虛擬現(xiàn)實(shí)眼鏡的光學(xué)鏡片直徑以及出瞳距離對(duì)視場(chǎng)角的敏感性做了分析,選擇了最優(yōu)的鏡片直徑和出瞳距離,采用Zemax軟件設(shè)計(jì)了相應(yīng)的球面和非球面鏡片。對(duì)二者的彌散斑和軸外相差進(jìn)行了對(duì)比,發(fā)現(xiàn)非球面鏡片可以顯著提高鏡片的成像效果,并應(yīng)用軟件消除了由鏡片導(dǎo)致的畸變。設(shè)計(jì)的非球面鏡片視場(chǎng)大、畸變小,達(dá)到了預(yù)期的效果。 c"jhbH!u4

Abstract: The angle of view of virtual reality head-mounted display is analyzed, optimizing the diameter of the lens and the distance of exit pupil. The spherical and non-spherical lens are designed and their disc of confusion and off-axis aberration is compared by using Zemax. The conclusion is that the non-spherical lens can improve the image significantly. Distortion resulted from the lens is corrected by the software. Non-spherical lens have little distortion and large viewing angle, which can satisfy our needs. ! 7#froh
