Abstract

An apparatus is provided for optically checking the inner profile of a tube or a bore, especially the tubes of steam generators in nuclear power stations, the apparatus includes a probe which is positioned within and is movable longitudinally within the tube or bore and is connected to an external power supply and analysis system. The probe includes a source of light, a mechanism for causing the light to illuminate the wall of the tube or bore along a line corresponding to the intersection of the wall with a cross-sectional plane, and a mechanism for forming an image of this line on a photo-sensitive sensor, so that variations in the inner profile of the tube or bore can be determined from deviations of the image from a theoretical image corresponding to the typical profile of the tube or bore.
