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 completed and compared with traditional Erfle eyepiece. The comparison results show that the refraction/diffraction hybrid eyepiece designed in this paper can make the HMD optical system achieve better design results, making it lighter and more compact.
