Endoscopic UV probe for high-pressure testing

Documentation of the complete UV probe system consisting of an optimized cooling jacket to protect the inner UV optic system against the thermal load inside the combustion chamber and the corresponding endoscope using miniaturized lenses and a flexible UV fiber image bundle for observation of the hydrogen flame behavior through OH* chemiluminescence at the DLR test facility. The development is carried out within T4.4.1 using software from T4.4.2 and related to the application in T4.5.
