Design of Refractive-diffractive Eyepieces with 70°Wide-angle Field of View;

广角70°视场折/衍混杂目镜设计

A head mounted display, which combines a Erfle eyepiece with a reflective relay system and uses a micro display of the reflective liquid crystal on silicon with the diagonal size 18mm, has been designed.

该系统由一个常用的艾尔弗 (Erfle)接目镜和一个反射中继镜组成。

The supplementary accommodation out of eyepiece is presented to solve problems in adjusting and applying instrument with ocular such as spectrometer.
