An image forming system includes a spatial light modulator (SLM) including a plurality of pixels. Each pixel is configured to diffract incident light and cause the diffracted light to exit the SLM, where a first diffraction order of light exiting the SLM passes through a first exit pupil and higher diffraction orders of light exiting the SLM pass through additional exit pupils having different positions from the first exit pupil. Control logic operatively coupled to the plurality of pixels is configured to control each pixel to control its modulation of the light incident on the pixel and cause the plurality of pixels to collectively form an image at each exit pupil.

A display may include illumination optics, a ferroelectric liquid crystal on silicon (fLCOS) panel, and a waveguide. The illumination optics may produce linear polarized illumination light that is modulated by the fLCOS panel to produce image light. The illumination optics may include light emitters that emit respective wavelengths of the illumination light. The illumination optics may include an X-plate that outputs the illumination light by combining the light emitted by the light emitters. Polarization recycling structures may be optically interposed between each of the light emitters and the X-plate. The polarization recycling structures may include a reflective polarizer. If desired, the polarizing recycling structures may also include a quarter waveplate. The polarization recycling structures may serve to minimize the amount of light lost in producing linearly polarized illumination light for the fLCOS display panel, thereby maximizing the optical efficiency of the display.
