Method and apparatus for testing composite optical components

Abstract

The invention relates to a method and an apparatus for testing the optical properties of a composite optical component which includes a multiplicity of connected transparent elements and reflection layers which are arranged so that light introduced at an input portion is split in a first segment of the composite component with a plurality of transparent elements into a multiplicity of first partial beams, which are guided along different paths in the composite component. The first partial beams are partially reflected multiple times in a second segment which also includes a plurality of transparent elements, so that a plurality of second partial beams emerges from a side face due to the partial reflection. The second partial beams are recorded by a detector, and a quality coefficient is ascertained for a plurality of second partial beams selected according to an aggregation rule so the quality coefficient is assigned to a particular part of the composite component.
