Since more than 30 years, the increased research, technology development and commercialization of optical fiber sensors combined with their continuously growing technical applications have become a story of success worldwide and in Germany as well. German fiber sensor research and industry achieved remarkable milestones in the 1980ies and 1990ies, such as first field tests of magneto-optic current sensors in power facilities or of micro-bending fiber strain sensors in a highway bridge. Recent progress and the state of the art of optical fiber sensing in Germany are demonstrated by examples of advanced fiber Bragg grating and distributed sensor system applications, fiber gyroscopes and other interferometric sensors, chemical and bio-medical sensors, and sensors based on polymer fibers as well. In context with the growing international cooperation, the potential of German research and industry will be discussed in terms of novel fiber-optic sensor system concepts, of increasing maturity and reliability of this exciting sensor technology and of new applications and markets.© (2011) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
