Abstract (en)
[origin: DE19860017A1] The invention relates to a device which is especially embodied as a projector head (60). Said device comprises a line mirror (12) which has at least one mirror surface (14) for deflecting the bundle of light in the line direction of the video image and an image mirror (16) for deflecting in the direction of the image. The normal to the surface (23) of the at least one mirror surface (14) is inclined under the angle epsilon in relation to the axis of rotation (33) of the line mirror (12). According to the invention, the bundle of lights (5) is incident to the surface mirror (14) under the angle (I), with epsilon ' = epsilon +/- 4 DEG to the normal to the surface, in the position of the line mirror (12) in which the bundle of lights (5) is directed to the centre of the video image in the main projection direction (28).
