The major European aircraft companies are engaged in a common project INCA (Improved NDE Concepts for Innovative Aircraft Structures and Efficient Operational Maintenance) to investigate laser ultrasonic technology in order to get the maximum performances of such a non-destructive testing (NDT) system. The INCA project was established to advance the state of the art of NDT to enable the aeronautic industry to manufacture aeronautic structures with new materials, new technologies, and new structural geometries with a quality assurance system using the best, fastest, safe, reliable and cost efficient NDT methods. A review of the laser ultrasonic developments undertaken and of the results achieved by the different partners of the INCA project is presented. The scientific approach of the INCA project is based on the setting-up of a test-platform, and the development of defined subsystems to evaluate the performances of the laser ultrasonic technology on new composite and metallic applications. New developments and major improvements concerning ultrasonic generation (thin disc laser, mid-IR OPO, UV module...), detection (new laser design, photorefractive interferometers...) and signal evaluation are the major goals within the INCA project as well as the reduction of the system's overall costs. Some significant achievements have already been obtained and some promising ones are expected to push forward the current limits of this technology. A better understanding of the involved phenomena on the one hand, and a more versatile offer on the other hand should be the major end-results of the project. However, an important issue is remaining at that stage, it concerns the necessary integration and support capacities in Europe to enable a large dissemination in the aeronautic industry and in others such as the steel one.
