  "textContent": "A head-up display for a transportation vehicle. The head-up display includes an imaging unit for generating an image, and an optical system for projecting the image onto a projection surface. The optical system includes at least a first mirror, a curved second mirror arranged adjacent to the first mirror, and a selectively reflective element configured in an optical path between the first mirror and the second mirror. The optical system is configured such that light emitted from the imaging unit is directed to pass through the selectively reflective element, reflected off the first mirror towards the selectively reflective element, reflected by the selectively reflective element towards the second mirror, and reflected by the second mirror towards the selectively reflective element, and passed through to be directed to the projection surface.",
