Abstract

An In-Vessel Inspection Systems (IVIS) which uses linear arrays of optical fibres, is proposed for ITER. The system is based on long rotating line scanning viewing probes, which provide a quasi-spherical field of view and high resolution picture of 480,000,000 pixels completing the inspection in a few minutes, without the need for mechanical adjustments of the focus and the aperture of their lens optical systems. The illumination is provided by pulsed laser beams. The duplication of the optics in each probe has also been considered for tridimensional distance measurements
