Patent ID: 7230229

Claim:
Method for detecting surface defects on the outer wall ( 2 ) of a transparent or translucent object ( 3 ), characterized in that it comprises the following steps: by means of a uniform, extensive, broad light source ( 4 ), sending an incident light beam ( 5 ) onto a surface of the outer wall ( 2 ) of the object, arranging a linear measuring sensor ( 8 ) to collect the light beam ( 9 ) reflected by a linear zone (Z) of the outer wall ( 2 ), illuminated by the light source ( 4 ), ensuring relative movement between firstly the object ( 3 ) and secondly the light source ( 4 ) and the linear measuring sensor ( 8 ), so as to move the linear measuring zone (Z) over the outer wall ( 2 ) of the object to cover the surface to be inspected, and processing the light beams ( 9 ) received by the linear sensor, so as to create an image (I) and to identify within the image the presence of a surface defect corresponding to a dark area (s).
