| Title: |
Method of Spatially Moving a Projection Beam From a Video or Graphics Projector |
| Abstract: |
In order to move spatially the projection beam from a video or graphics
projector, the projection beam which emerges from a light source and is
guided via and/or through an optoelectronic image generator and through a
projection lens is deflected by means of at least one mirror which can be
pivotably displaced about two axes, an X-axis extending in the direction
of incidence of the projection beam and a transverse Y-axis. In order to
attain perfect correction of the image distortion caused by rotation in
spite of the rapid movement of the mirror, the images to be projected from
the image generator are further rotated when the mirror is pivotably
adjusted about the X-axis in forced coupling with the pivotal adjustment
of the mirror in order to compensate any image distortion occurring.
