Original Abstract Submitted

a multi-focal system includes a display pixel array, a pixelated polarization array, and a pancharatnam-berry phase (pbp) lens. the display pixel array includes a first display pixels generating first display light and a second display pixels generating second display light. the pixelated polarization array has first pixels and second pixels. the first pixels are aligned with the first display pixels to generate a first polarized light having a first polarization orientation. the second pixels are aligned with the second display pixels to generate a second polarized light having a second polarization orientation different from the first polarization orientation. the pbp lens is configured to focus the first polarized light having the first polarization orientation to a first focal length and focus the second polarized light having the second polarization orientation to a second focal length that is greater than the first focal length.
