Device and method for detecting and / or investigating a Abtrag on a surface of a cylindrical member

摘要

The invention relates to a device (2) and a method for detecting and / or examining a removal (4) on a surface of a cylindrical component (8), in particular a rod-shaped component of a nuclear power plant, in particular a fuel rod, a control rod, a neutron source rod, a An absorber bar and / or a lance, comprising a light source (10) for projecting light onto a surface area (6) of the cylindrical component (8), an image capture unit (12), in particular a camera for capturing an image of the surface area (6) on which Light is projected and / or for examining the surface area (6) of the cylindrical component (8), wherein the light source (10) is a slit lamp which emits light in a light beam plane (E) and the optical axis (A) of the image acquisition unit ( 12) is oriented at an angle (α) to the light beam plane (E) of the light source (10).
