Abstract
A flat disk contains a number of holograms made from the interference of a plane wavefront with spherical wavefront modified by a first cylindrical lens. The disk is rotated so that a plane reconstruction wavefront sweeps across the holograms. The resulting reconstructed wavefront is passed through a second cylindrical lens, resulting in a focussed point sweeping across an object surface in one or more substantially straight lines.
