Projection device has projection arrangement movable by movement arrangement so optical axis of projection beam remains at essentially constant angle to projection surface during motion

摘要

The projection device has a projection arrangement (30) for producing an image (40) on a surface (10). The projection arrangement is movable by a movement arrangement (20) so that the optical axis of the projection beam remains at an essentially constant angle to the projection surface during the movement. The projection arrangement is movable at a constant distance from the projection surface. AN Independent claim is also included for the following: a method of projecting an image with an inventive device.
