ABSTRACT:
Method for performing the automatic contactless inspection of objects manufactured at a high speed by an automatically controlled machine, in particular high-temperature glass objects, the objects moving in front of an optical measuring device, consisting in illuminating the moving objects with a non-coherent white light, sensing the transmitted light by means of an optical sensor (5) provided with a linear measuring strip (2) comprising a plurality of receptor photodiodes (3), the strip (2) being arranged with its longitudinal axis perpendicular to the movement of the objects (6) and to the focal point of a focusing lens (9), and storing the result of the sensing operation for a given number of objects.
