采用分立元件研制双目光学透视式头盔显示器,对双目透视式头盔显示中的关键问题进行实验研究.用偏振分光棱镜作为组合镜,通过理论分析,发现图像源和外界环境的亮度随偏振片方位角呈余弦变化规律,并通过调整偏振片使头盔显示器的图像与外界环境达到最佳融合状态.调查研究了头盔显示器双目重叠范围的改变对视觉效果的影响,数据结果显示,双目重叠范围为单目视场的33～50%时效果最佳.最后根据视差原理编程制作立体图像对,分别显示于头盔显示器的左右眼,实现立体显示.

The binocular see-through optical Head-mounted Display(HMD)is developed by using discrete elements,and the key problems in the HMD are researched.Using polarization beam splitter as combiner,it is found that the brightness of HMD and outside environment has cosine variation with the polarizer azimuth through theoretical analysis.Then,the image of HMD can mix together with outside environment excellently by adjusting the azimuth angle of polarizer.The vafimions of HMD vision effect which change with the rotation of polarizer are investigated,and the results indicate that the effect is optimal when the binocular overlapped range is 33~50%of the monocular field of view.At last the stereoscopic display of HMD is realized by the stereo image pairs which are made according to the parallax theory.
