Developed for the inspection of the ITER machine, the technology is based on a Frequency Modulated (FM) LIDAR for absolute distance measurements and amplitude modulated (AM) LIDAR for surface viewing. Its final objective is to perform 3D mapping of the elements to detect any damage or erosion of components that occurs during operations. An optical test bed with reduced dimension prototype has been built to validate these performances.
This solution offers the possibility to measure small objects at large distance with high accuracy through raster scan and 3D reconstruction. Current instrument’s performance show a depth accuracy down to 0.006mm and a lateral resolution between 0.1mm and 1mm for a measurement range of 10m at 2000 data points per second. These requirements can be customized according to application and it is also possible to increase the compactness of the measurement head for easier integration.
