A compact see-through head-up display (HUD) for a vehicle (e.g., an aircraft) is implemented as a stationary display, a head-mounted display, a helmet-mounted display, or the like, positionable in front of a user (e.g., a pilot). The HUD may be provided as an integrated stack-up including a see-through emissive display positioned between a predetermined number of first and second optical counterparts, each optical counterpart including a wave plate coupled with a polarization directing lens. The first optical partner is configured to collimate display light emitted from a display side of the see-through emissive display, and the second optical partner provides an equal and opposite focus cohesive effect to counteract the focus cohesive effect of the first optical partner, the see-through emission type display does not affect the focal length of the external environment watched by the see-through emission type display. 一种用于交通工具（例如，飞行器）的紧凑型透视平视显示器（HUD），其被实现为可定位在用户（例如，飞行员）前方的固定式显示器、头戴式显示器、头盔安装式显示器等。所述HUD可以作为集成叠层
