During the manufacturing / assembling process of an aircraft, or in service after delivery, surface damages may occur on external side of the fuselage. Most of those defects are small compared to the size of the aircraft and are generally spread out on the whole surface of the fuselage. In order to characterize properly these kind of anomalies, new means are always wanted in the field of Non Destructive Testing. They need to be reliable, portable, fast and accurate. For this kind of defect, optical techniques offers usually good solutions. Then, new technologies based on optics are developped to meet the requirements of the aircraft manufacturer in terms of damages characterisation. Particularly, a portable device, based on the shadow moire effect, was developped to characterize the exact geometry of impact damages on aircraft fuselage. The system is easy to use, portable, fast and low cost. It will help the operators in terms of defect classifications and will allow a substancial time saving during the inspection. After a test period, the device should be used in the Final Assembly Lines of aircrafts.
