Abstract
A two-dimensional light deflector is shown which comprises a cylindrical member having a plurality of holograms recorded thereon. A collimated light beam is directed to illuminate the hologram cylinder and rotation of the hologram cylinder provides a line scan which is at an angle of about 45.degree. with respect to the plane of rotation of the cylinder. The azimuthal position of the line scan can be varied by the rotation of a small mirror which directs the illumination beam. As a consequence, a two-dimensional raster scan on a cylindrical image surface is produced.
