Zusammenfassung:	Apparatus and method for optical inspection of a pipeline ( 2 ) for transporting fluid ( 3 ) by internal surveying. Light source means ( 4 ) are adapted to form one or more beams of light ( 5 ) illuminating a line (L) of a surface part ( 9 ) of said pipeline ( 2 ). Optical receiving means ( 6 ) are positioned outside a plane formed by said beams ( 5 ) and arranged to have in its field of view ( 7 ) the line (L) formed on the internal wall of the pipeline ( 2 ) by the beam ( 5 ). The receiving means ( 6 ) are adapted to form a two-dimensional indexed images ( 20 k) each comprising intensity data for a predetermined number of pixels in each of a predetermined number of lines (M) of said image ( 20 ). A data processing unit ( 100 ) including an image analyzer module ( 110 ) is adapted for extracting a depth profile of said surface ( 9 ).
