Abstract: The present disclosure relates to a landing assistance system and method (100) for assisting an airborne vehicle (1) during landing on a landing area (2). The landing assistance system (100) provides the airborne vehicle (1) with light signals. The landing assistance system comprises at least one geographically positioned light emitter (4, 6, 8) arranged at near ground level on the landing area (2). At least one first light emitter (6) of the at least one geographically positioned light emitter (4, 6, 8) is arranged to emit light to a designated position in space. The light comprises at least three light beams (B1-B3), wherein a first beam (B1) being a central beam, which indicates a designated glideslope, and at least a second beam (B2) and third beam (B3) indicating that said airborne vehicle (1) is positioned under or above the designated glideslope, respectively.

Abstract: The present disclosure relates to an image generator device (100) for changing the direction of at least one emitted light cone at a surface (113), comprising an image generator (130) and a fibre optical faceplate (110) having a first (112) and a second surface (113), the fibre optical faceplate (110) being arranged to transmit light from the image generator (130) so at least a part of light entering the first surface (112) of the fibre optical faceplate (110) exits through the second surface (113) of the fibre optical faceplate (110) and pass through an aperture, wherein the fibre optical faceplate (110) comprises a multitude of optical fibres (111) and light exiting the second surface (113) through optical fibres (111) each form an emitted light cone. A surface structure (120) is arranged at the second surface (113) of the fibre optical faceplate (110), wherein the surface structure (120) is arranged to changing the direction of at least part of the emitted light cones exiting the second surface (113) of the fibre optical faceplate (110) towards the aperture.
