ABSTRACT:
A light scanning system for moving a light beam across a straight surface. The system includes a laser light source, a rotating holographic disk deflection system, and a multielement F.theta. lens constructed entirely of holographic plates. The holographic plates are offset from each other in the beam path and have parameters which cause the holographic plates to optically cooperate with each other to produce uniform spot size and scan velocity. Specific construction parameters and methods are outlined along with particular materials and parameter ranges.
