Non Destructive Testing Lab

Ultrasonic Testing

Large Air-coupled Ultrasonic Scanner providing C-scan data volumes (spatially resolved time signals). The sensor is a consumer MEMS microphone, the stimulus signal is coupled via the back surface of test structure (here a self-manufactured Fibre-Metal laminate plate with structural defects)

Small Air-coupled Ultrasonic Scanner providing C-scan data volumes (spatially resolved time signals). The sensor is a consumer MEMS microphone, the stimulus signal is coupled via the back surface of test structure (here a Fibre-Metal laminate plate provided by the Faserinstitut Bremen and pseudo-defects applie dto the plate surface)

X-ray Testing

Micro-Focus Xray radiography and CT measuring device with shielded measuring chamber containing the X-ray source (micro-focus Oxford Instruments, 93508, Cu target, 50W, 35μm FSD), linear and rotational motion stages for probe positioning and the X-ray tube and detector controller.

Inside view of the X-ray tube and detector controller (coupled to local Ethernet) with controllable and regulated High-voltage supply (50 kV, 1 mA).
