Project Description

A self-optimizing 4.0 production environment places high demands on the sensors for quality monitoring. What is needed are versatile, multifunctional optical sensors, which are particularly suitable for inline 100% production monitoring due to their high measuring speed.

In this project, a multifunctional chromatic measuring principle is pursued, which allows both confocal and texture-based 3D measurements. Depending on the test task, different measuring principles are used, which are implemented in highly integrated optics. As a central innovation, a self-optimizing, adaptive measuring method is proposed. State-of-the-art 3D measuring methods scan the entire measuring range with high resolution to solve a test task. By contrast, adaptive signal processing pursues a coarse-to-fine strategy, in which the measurement and is conducted more and more precisely in an iterative process. This effectively scans only at interesting and information-bearing locations with high resolution. This novel approach promises significantly higher measuring speeds.
