摘　　要：经过理论分析和计算,结合加工难度,提出了对全息波导显示系统中全息波导板的优化方法。对28°圆视场、30 mm×30 mm系统出瞳的全息波导显示系统中的全息波导板进行了优化。输入全息光栅尺寸、分束膜尺寸和输出全息光栅尺寸分别为5 mm×30 mm,30 mm×30 mm和30 mm×30 mm,波导板材料、波导板厚度、上波导板厚度和下波导板厚度分别为Ba K7,3 mm,0.75 mm和2.25 mm时,能够满足所要求的全息波导显示系统视场和出瞳性能要求。通过优化得到的系统构型可以应用于全息波导头盔显示器、全息波导平视显示器等。A new method for optimization of the holographic wavegtfde plate in a holographic waveguide display is proposed according to theoretical analysis, calculations and manufacture difficulty level. A waveguide plate for a holographic waveguide display system, with 28° field of view and a large exit pupil about 30 mm× 30 mm, is optimized by this method. The performances of this holographic waveguide display system can be satisfied by an input holographic grating of 5 mm× 30 mm, an output holographic grating of 30 mm×30 mm, together with a glass （BaK7） waveguide of 3 mm thickness, which is divided into two waveguides, one has 0.75 mm thickness and another 2.25 mm, by the beam splitter. This configuration can be applied to a Head-Mounted Display（HMD） or a Head-Up Display（HUD）.
