1. A display comprising:

  • a source that establishes an exit pupil of far field content;

    a reconvergent sheet disposed along an optical axis to receive light of the far field content, the reconvergent sheet being configured to implement a phase-corrected Fourier transform to reconverge the far field content in position space;

    a reflective surface disposed along the optical axis for reflection of light of the position space back through the reconvergent sheet after reflection off of the reflective surface to re-form the exit pupil of the far field content; and

    a splitter disposed along the optical axis between the source and the reconvergent sheet and configured to redirect light exhibiting the re-formed exit pupil in a direction offset from the optical axis.
