Patent Number:	6416183
Title:	Apparatus and Method for Three-Dimensional Movement of a Projected Modulated Beam
Abstract:	The present invention to provides a projection system for three-dimensional movement of projected modulated beam. It comprises a stationary light source, a projection lens, an optical path from the light source to the projection lens and a light beam modulating element in the optical path. The light modulating element moves with the projection lens. The image is generated at a location whereafter the modulated beam is not deflected anymore before arriving at the projection lens. Therefore there is no rotation of the modulated light beam around its own optical axis, independent of the direction of projection.
