    The near-eye aperture is used to realize the super multi-view display based on time multiplexing because it effectively limits the divergence angle of the light beam emitted from a display screen. Therefore, a large depth of field can be achieved. However, its small size also exerts a serious limitation on the field of view that can be obtained using only one near-eye aperture. This limitation can be successfully overcome by designing timing sequentially gated multiple groups of near-eye apertures and splicing up the display regions corresponding to different apertures in the same group. However, the light emanating from each display region may pass through non-corresponding apertures, thus creating a new problem of crosstalk noise. To address these problems, mutually orthogonal characteristics are endowed to the adjacent near-eye apertures in this work, which makes the light emitted from each display region with an orthogonal characteristic be blocked by the adjacent apertures of its corresponding aperture and forms a certain range of noise-free region in the observing plane. This foundation allows for the realization of a super multi-view display with a large field of view based on near-eye apertures. In this study, a proof-of-concept head-mounted super multi-view display system is constructed and M one-dimensional strip-type apertures are composed as a group, in which two adjacent apertures, respectively, only allow light with mutually perpendicular polarizations to pass through. Based on the persistence of the vision, T groups of timing sequentially gated near-eye apertures are used to realize the super multi-view display with T viewpoints for each eye and M times larger field of view compared with the case where only one aperture opens at each time point. This work only takes M=3 for verification and gets an expanded field of view of 19.7° due to the limitations by optical performances of the used convention projection lenses.
