Specular gloss is an important measurand used in quality control of manufacturing processes of highly reflective parts. In this work we present an in-process quality control system to evaluate the gloss of free-form surfaces to be used in an automated polishing process. Due to the geometry of our test objects the presented sensor is mounted on a robot arm and, therefore, needs to be robust against sensor misalignment. This robustness is achieved using a 2D CCD-camera as detector which allows us to properly handle sensor orientation deviations of up to 10. The required dynamic range of the sensor is obtained based on the acquisition of high dynamic range images. We present first results of a sensor prototype and show its applicability to the target application.
