| 摘要 |
The invention relates to a redundant back projection display system (100) for an aircraft comprising at least two separate light sources (1, 3), at least one optical combiner (4, 5), fed with image/video by at least one of the at least two separate light sources (1, 3), at least one lens (8, 13), fed by the at least one optical combiner (4, 5), and at least one projection screen (10, 14), fed by the at least one lens (8, 13). A third light source (2) is provided and at least one splitter (6) as an optical element, said splitter (6) being fed by the third light source (2) to pass on at least one split share from the third light source (2) towards the at least one optical combiner (4) to optically combine said at least one split share with the image/video emitted from the one of said at least two separate light sources (1) for optical combination towards the at least one projection screen (10). |
