The video system with a CCD-Micro-Camera allows the detection of the sparks within the structure. The camera itself with a diameter of 25 mm and a length of 120 mm is protected against the electromagnetic field by a faraday cage. The signal will be transferred by a fibre optical link to the receiver in the measuring cabinet. The signal of the camera will be stored with a digital video recording system, using the data compression procedure M-JPEG. The development of the spark will be recorded by about one or a few pictures, supported by the slow reaction of the camera on the fast brightness change of the real spark. The experiences with the camera system have shown that this is a reliable tool to detect sparks during the test of direct effect of carbon fibre reinforced structures and provide the possibility to detect sparks also within closed components.
