摘要
分析了离轴、大视场角透视型头盔显示器光学系统的设计方法,提出了利用衍射光学的独特性质设计了大视场、宽波段、离轴折/衍混合透视型头盔显示器光学系统.该系统具有10 mm的出瞳直径和22 mm的出瞳距离,且满足人因素要求.另外,该系统色差仅14μm,系统口径小于46 mm,满足双目视觉要求.整个系统适合具有15 mm对角直径SVGA分辩率的彩色液晶显示器(LCD) .
Design of a wide-angle off-axis optical see through helmet-mounted display （HMD） becomes a challenge since its weight and size are constrained by human factors. Diffractive optics has the potential to play a key role in several areas of head-mounted display. They can reduce size and weight while providing some unique functions that would be difficult to implement with conventional refractive optics. A 60°-diagonal field-of-view, wide spectral band hybrid diffractiverefractive see-through HMD using off-axis optics is proposed. It possesses a 10mm exit pupil diameter and a 22mm eye relief, and satisfies the requirements of human factors. In addition, the chromatic aberration is only 14μm,and the whole optical system is suitable for a 15mm-diagonal color liquid crystal disolay （LCD） with SVGA resolution.
