**About the Editor**

**Andreas Fischer** is Full Professor at the Department of Production Engineering, University of Bremen, in Germany and is head of the Bremen Institute for Metrology, Automation and Quality Science (BIMAQ). He studied electrical engineering and completed his PhD at the Technische Universitat Dresden. As one of several awards, he received the Measurement Technique Prize 2010 ¨ of the Society of University Professors of Measurement Technique in Germany. In 2021, he further received a prestigious ERC Consolidaor Grant for enabling indirect optical geometry measurements. His research interests include optical measurement principles for flow and production metrology, their near-process or in-process application, and the information theoretic analysis of achievable measurement uncertainty to surpass the current limits of measurability.
