Paper Abstract

A universal, extended dynamic range novel optical inspection system for aspheric optical components and optics that are not easily inspected with conventional interferometry is presented. Modern optical design and manufacturing procedures have begun using such components more and more in routine applications to improve optical system capability. Inspection tools required for these types of optical components have lagged the capability to manufacture them. In this paper unique measurement procedures employing digital holography combined with a spatial light modulator are discussed for complex shapes such as aspheres and mandrels.
