An optical device includes a light source configured to provide a light beam. The optical device includes a light source configured to generate a light beam, and a spatial light modulator (“SLM”) configured to modulate the light beam to provide a hologram for generating a display image. The optical device includes a polarization-selective steering assembly configured to provide a plurality of steering states for the modulated light beam. The optical device includes an image combiner configured to focus the modulated light beam steered by the polarization-selective steering assembly to generate an array of spots at an eye-box of the optical device.
