摘要
在一个7片物镜的基础上,设计出一个折射和一个5片镜的折衍混合投影物镜系统,并给出了详细设计过程及性能评价。系统针对33.02 mm(1.3英寸)微显示器设计,视场为56°,出瞳直径为10 mm,出瞳距离为25 mm。设计的折射系统和折衍混合系统的镜头直径分别为28 mm和22.4 mm,重量分别只有33 g和11.9 g,且最大畸变分别为3.2%和0.17%,分辨率满足SXGA显示模式。两系统均满足投影式头盔显示器在交互环境、医学可视化训练和数字化个兵等领域的使用要求。
Abstract
Based on a 7-element lens, a refractive lens system and a 5-element hybrid refractive-diffractive lens system are designed. The optimization procedure and the performance of the systems are presented in detail. The systems are desigzned for a 1.3 inch (~3.3 cm) liquid crystal display (LCD) with 56° field of view, 10 mm exit pupil diameter and 25 mm eye relief. The refractive projection system has a 28 mm diameter and 33 g weight. And the hybrid refractive-diffractive system has a 22.4 mm diameter and 11.9 g weight only. The maximum distortions of the two systems are less than 3.2% and 0.17%, respectively. Both the refractive and the hybrid refractive-diffractive system can display SXGA mode images, act as projection system of head-mounted projective displays (HMPDs) in the fields of medical collaborative environments, medical visualization for training, soldier equipped with digital system, and so on.
