ABSTRACT:
A laser beam generated from a laser source is passed through a semi-cylindrical lens having a horizontal axis and vertically converged thereby to a horizontal line on a face of a rotating multi-face mirror. The vertically converging light beam is reflected by the face of the mirror and vertically diverges. The vertically diverging light beam impinges on a hologram and the first-order diffraction beam emerging from the hologram converges to a point. As the mirror rotates about the axis of rotation thereof, the point to which the first-order diffraction beam converges repeatedly moves along a line of predetermined length. The hologram has the effect of converging the first-order diffraction beam emerging therefrom when it receives a vertically diverging light beam so that any beam emerging from vertically the same level on the face of the mirror converges to the same point.
