ABSTRACT:
The present invention includes a rotable disk type of hologram which deflects an incident light beam such as a laser into an intermediate scanning path of a curvilinear configuration. An extended prism provides a variable incident angle surface for refracting the incident curvilinear configuration into substantially a linear scan path on an object surface.
