In optical scanning apparatus useful, e.g., for high speed digital communication of photographic images, a light source is arranged to produce a beam incident on a rotatable reflector along a path forming an acute angle with the scanning surface defined by the sweep of the reflected beam, and the scanning axis about which the reflector rotates is tilted with respect to the surface of the reflector and toward the scanning surface from the side thereof on which the beam is incident on the reflector, the axis thereby forming an acute angle with the scanning surface, the arrangement producing a desired approximation of planarity of the scanning surface. |
