| Zusammenfassung: | A device for linear scanning includes a roof prism. The roof prism includes a roof of two mutually perpendicular reflecting surfaces intersecting in a line of intersection. A scanning mechanism moves the roof prism in a direction perpendicular to a plane of bilateral symmetry. The line of intersection is included in the plane of bilateral symmetry; and an incident beam entering the prism and an exit beam exiting the prism are angularly separated by a substantial angle. Preferably, the scanning mechanism generates periodic motion or rotational motion of the roof prism with a radius of motion greater than a dimension of the roof prism. |
