13.10.2023 Congratulations to Bian Qiang on the successful defense of his dissertation in the field of fiber optic sensing.
-
For this purpose, Dr.-Ing. Bian developed corresponding novel fiber optic sensor networks in the photonics laboratory, which could be embedded in aluminum and copper components during the casting process. As a scholarship holder of the Chinese Scholarship Council, he decided to do his doctoral thesis in cooperation between the TUM-MST and the HM Laboratory for Photonics.
