ABSTRACT:
A microdeflector facet tracker comprised of a flexible finger supported for bending movement on a base, the finger having a conductive highly reflective coating on the outside thereof to reflect a beam of high intensity light against the facets of a rotating scanning element, the finger progressively deflecting in response to the application of progressively increasing electrical potentials applied with each facet so that the beam is tracked with each facet as the facet moves past thereby maintaining the point at which the beam impinges against the facets substantially constant, the electrical potential being removed between each scan line to permit the finger to return to an undeflected position preparatory to the next scan line.
