Abstract: Polymeric, birefringent reflective polarizers have been used to produce compact, mid-field-of-view eyepieces and
wide field-of-view optics for virtual reality (VR) head-mounted displays using the “pancake” lens configuration.
Multiple configurations for pancake lens systems are discussed as are their advantages and disadvantages relative to
refractive systems. Polarization control is an important consideration and the polarizing effects of different
components are discussed. Designs for mid-FOV and wide FOV are presented and additional benefits of using
folded optics for virtual reality systems are explored.

文章的摘要：Virtual reality head-mounted displays (VR-HMDs) are crucial to Metaverse whichappears to be one of the most popular terms to have been adopted over the internet recently. It
provides basic infrastructure and entrance to cater for the next evolution of social interaction, and
it has already been widely used in many fields. The VR-HMDs with traditional aspherical or
Fresnel optics are not suitable for long-term usage because of the image quality, system size, and
weight. In this study, we designed and developed a large exit pupil diameter (EPD), compact,
and lightweight VR-HMD with catadioptric optics. The mathematical formula for designing
the catadioptric VR optics is derived. The reason why this kind of immersive VR optics could
achieve a compact size and large EPD simultaneously is answered. Various catadioptric forms
are systematically proposed and compared. The design can achieve a diagonal field of view
(FOV) of 96° at -1 diopter, with an EPD of 10mm at 11mm eye relief (ERF). The overall length
(OAL) of the system was less than 20 mm. A prototype of a compact catadioptric VR-HMD
system was successfully developed.
