This paper introduces a polarized catadioptric virtual reality optical system. With a focus on the issue of serious ghost image in the system, root causes are analyzed based on design principles and optical structure.
The distribution of stray light is simulated using Lighttools, and three major ghost paths are selected using the area of the diffuse spot,
and the energy ratio of the stray light, K as evaluation means. A method to restrain the ghost image through optimization of the structure of the optical system by controlling the focal power of the ghost image path is proposed. Results/Conclusions The results show that the
for the ghost image path increases by 40% and K decreases by 40% after optimization. Ghost image is effectively suppressed, which provides the theoretical basis and technical support for ghost suppression in a virtual reality optical system.
Keywords: Virtual Reality ; Optical System ; Ghost ; Focal power ; Optical Design
