Zusammenfassung:	A compact see-through head up display (HUD) for a vehicle such as an aircraft implemented as a fixed display positionable forward of a user (e.g., pilot), a head worn display, a helmet mounted display, etc. The HUD may be provided as an integrated stack including a see-through emissive display positioned between a predetermined number of first and second optical pairings each including a waveplate coupled with a polarization directed lens. The first optical pairing is configured to collimate display light emitted from a display side of the see-through emissive display and the second optical pairing provides an equal and opposite focal vergence effect to counter the focal vergence effect of the first optical pairing such that the see-through emissive display does not affect the focal distance of the outside environment as viewed through the see-through emissive display.
