Abstract: A projection apparatus includes an image-producing element and projection optics. The image-producing element produces at least one image, and the projection optics has free-form areas for magnifying and reflecting the image toward an viewer for observation. The projection optics includes at least a first mirror and a second mirror, the image is reflected by the first mirror and the second mirror in succession, no deflection mirror is disposed between the viewer and the second mirror, and the first mirror and the second mirror are in the form of a non-rotationally symmetrical system.
