Aberration‐free pupil steering Maxwellian display with wide‐view broadband polarization converters

Abstract

A see-through Maxwellian display with aberration-free pupil steering is proposed and experimentally demonstrated. The system uses a polarizationdependent off-axis lens coupler set fabricated with cholesteric liquid crystal. Electrically addressable polarization converters are used to switch among pupils. A wide-view broadband polarization converter is designed accordingly.

P‐90: Evaluating Maxwellian view design with a non‐equal weighting matrix

“…It is rather desired that the optical system continuously follow the gaze angle of the eye. In previous studies, the deflected beam from different FOV is considered equally in [9] by Li et al However, this would lead to a non-ideal design, as the resolution of the human retina is much higher near the center of gaze.…”

Planar liquid crystal polarization optics for augmented reality and virtual reality: from fundamentals to applications

“…Using the above-described polarization-dependent LC optical elements, we can steer the viewpoint in an elegant way, without the need of mechanical components [106,107]. As sketched in Fig.…”

Switchable polarization volume gratings for augmented reality waveguide displays

“…4,5 Although PVGs have not been adopted into commercial AR products, they are a promising candidate for waveguide couplers. [6][7][8][9][10][11][12] Both passive and active PVGs have been developed; the former uses an LC polymer, and the latter uses an electrically switchable LC material. Passive PVGs have been investigated extensively and integrated into waveguide plates as an input or output coupler to deliver AR images to the user.…”

“…The PVG is a slanted self‐organized cholesteric liquid crystal (CLC) structure, which induces selective diffraction in wavelength and incident angle 4,5 . Although PVGs have not been adopted into commercial AR products, they are a promising candidate for waveguide couplers 6–12 …”
