1. A display system comprising:
at least one display panel;
a field-evolving cavity;
a system enclosure;
the field-evolving cavity further comprising at least one semi-reflective element and at least one reflective element;
the field-evolving cavity being in optical communication with the at least one display panel;
the field-evolving cavity and the at least one display panel being mounted within the system enclosure;
the field-evolving cavity being configured to generate at least one virtual image with at least one focal plane along an optical path directed towards a viewer; and
the field-evolving cavity being configured so a portion of the optical path is folded back onto the optical path to adjust a depth of the at least one focal plane along the optical path.
