Abstract

Light deflector 1 has mirrors 2 and 3 positioned at an angle to one another about a cylinder. Mirrors 2 and 3 form a screw thread for scanning a light beam generated at light source 5 across a target 6 while maintaining a constant light path length. Rotation of deflector 1 about axis 7 moves the position of the thread relative to source 5 for scanning the beam across target 6. Flyback of the beam is accomplished by displacing the threads at seams 8.
