A microelectromechanical (MEMS) scanner, comprising: an optical element characterized in that: the optical element is configured to pivot about an axis between a first position and a second position, wherein the optical element is capable of one of transmitting light and reflecting light; and two or more Bragg polarization gratings (BPGs) (170, 171) provided on or above a planar surface of the optical element, the two or more BPGs (170, 171) configured to: receive light from one or more display engines, the light polarized into first and second polarizations; and transmit the first polarization of light in a first direction and transmit the second polarization of light in a second direction, wherein the first polarization of light is transmitted in the first direction forming a first portion of a field of view of the image as the optical element pivots about the axis, wherein the second polarization of light is transmitted in the second direction forming a second portion of the FOV of the image as the optical element pivots about the axis, the second portion of the FOV being different than the first portion of the FOV; and wherein the two or more BPGs are further configured to transmit the first polarization of light by diffracting a positive first order of the first polarization of light in the first direction, and wherein the two or more BPGs are further configured to transmit the second polarization of light by diffracting a negative first order of the second polarization of light in the second direction. an optical element characterized in that: the optical element is configured to pivot about an axis between a first position and a second position, wherein the optical element is capable of one of transmitting light and reflecting light;
