摘　　要：针对应用传统Erfle目镜的HMD光学系统的小型化和轻型化的发展需求,设计了一种改进的可应用于HMD光学系统的目镜。从HMD光学系统原理与设计参数两方面分析了对HMD系统进行改进的可行性;阐述了HMD系统应用BOE的优势;设计了一种基于BOE的折/衍混合目镜,并与传统Erfle目镜进行了对比分析。结果表明,设计的折/衍混合目镜可以使HMD光学系统体积、质量更小,结构更紧凑,成像质量更高。In this paper,an improved eyepiece for HMD optical systems is designed,which is based on the development of miniaturization and light weight of HMD optical systems using traditional Erfle eyepieces.Firstly,the improvement potential of HMD system is analyzed from the aspects of HMD optical system principle and design parameters.Then the advantages of applying BOE to HMD system are analyzed.Finally,the design of BOE based refraction/diffraction hybrid eyepiece is com pleted and compared with traditional Erfle eyepiece.The comparison results show that the refraction/diffraction hybrid eye piece designed in this paper can make the HMD optical system achieve better design results,making it lighter and more com pact.
