Abstract

This paper describes the implementation of an automatic focus control system (Autofocus) to an optical non-contact surface profiling instrument. Such a focus control system extends the operation of the surface profiler to measurements of both roughness and figure that would otherwise be limited by the optical systems depth of focus. Measurement results are presented from a variety of curved samples.
