    Abstract: The invention relates to a method for analyzing, by means of a light source (5) having a lighting surface (S) and by means of a camera (6) having an optical observation axis (A), a mark (2) made on the outer surface (3i) of a curved wall (3) made of a translucent or transparent material, characterized in that: - the extended, uniform light source is produced such that: the area of the virtual image (S1) of the lighting surface (S) of the light source (5) completely covers the surface of the mark (2), and such that the luminance of the virtual image (S1) of the lighting surface (S) of the light source (5) is uniform; and – the surface of the mark (2), placed over the surface of the virtual image (S1), is observed so as to enable analysis of the mark (2).

    Abstract: The invention relates to an in-line optical method of inspecting transparent or translucent objects (2) running at high speed between a light source (3) and means (4) for taking images of the objects and for analyzing the images taken, so as to detect defects in the objects. According to the invention the method consists: in controlling the single light source (3) so that said source produces in succession two types of illumination for each object running past said source, the first type being a homogenous illumination whereas the second type is formed from alternate dark zones and light zones with a discontinuous spatial variation; in taking images of each running object when each of them is illuminated in succession by the two types of illumination; and in analyzing the images taken with the illuminations of the first and second types for the purpose of detecting high-contrast defects and low-contrast defects respectively.
