Abstract

Present large scale fusion research reactors need imaging and metrology systems to make a survey of the status of the in-vessel plasma facing components in order to detect damage or evaluate erosions. The paper outline a solution based on a laser radar scanning probe. The probe is carried and inserted in the machine by a long harm, then there is the possibility that vibrations could arise in the probe, induced by the movements of the scanning head or by other vibration sources present in the machine like the vacuum systems. A dedicated test campaign was performed to evaluate how viewing and metrology produced by the laser radar are affected by vibrations at low frequency (f < 2 Hertz, and amplitude in the order of 0.5-2 mm). Furthermore a vibration correction algorithm was developed to cancel the vibrations effects in post processing.
