| Zusammenfassung: | The optical arrangement for a one-piece helmet visor (31), connected by an optical relay (30) to an image source, has the visor in the form of a surface of revolution with its axis parallel to the wearer's optical axis and contained within his saggital plane on a level with the forehead. The relay consists of a non-flat frontal mirror (343) with its axis of revolution coinciding with that of the visor, and has geometrical parameters so that the envelope of the useful beams passing between the frontal mirror and the first image former (341) of the optical relay above the frontal mirror is contained within a cylinder of equal section to the useful surface of the mirror. |
