Förfarande och anordning för överlagring av en bild på en direkt omvärldsbild för att presenteras en observatör

摘要

The present invention relates to a method and an arrangement for superimposing an image on a direct image of the surroundings in order to be displayed to an observer (7). To generate the image which is to be superimposed on the direct image of the surroundings use is made of a line transmitter (1) for transmitting two-dimensional image information in linear form and a converter (2) for converting the image information in linear form into a two-dimensional image. The line transmitter (1) is located in a different direction from the image of the surroundings of the observer, and a direction-changing means (3, 4) is arranged so as to angle the radiation from the line transmitter in a direction towards the eyes (8) of the observer (7). According to the invention the converter (2) is separate from the line transmitter and arranged in proximity to the direction-changing means.
