Anzeigevorrichtung für Helmvisier
The helmet viewer has a holographic reflecting surface (11) along the axis of the pilot's eye (AA) which reflects laser light and allows direct light to enter from the scene. Laser information from a laser source (12) is focussed (14a) onto an upper reflecting plate (15a) and onto an upper surf...

| Zusammenfassung: | The helmet viewer has a holographic reflecting surface (11) along the axis of the pilot's eye (AA) which reflects laser light and allows direct light to enter from the scene. Laser information from a laser source (12) is focussed (14a) onto an upper reflecting plate (15a) and onto an upper surface of the front reflector (16a). The laser beam is then reflected from a second plate (15) on the plane between the eye and the laser, to be reflected onto the holographic surface. The holographic surface is corrected for aberration using interference fringes. |
