Abstract
PCT No. PCT/DE88/00758 Sec. 371 Date Jul. 23, 1990 Sec. 102(e) Date Jul. 23, 1990 PCT Filed Dec. 9, 1988 PCT Pub. No. WO89/05468 PCT Pub. Date Jun. 15, 1989.An apparatus for optically scanning a reflective object includes a first reflector having a frustoconical reflecting surface with a central opening. A second reflector has a flat reflecting surface which faces the frustoconical surface and is inclined with respect to the axis thereof. To the side of the flat surface is an optoelectronic sensor which is connected to a processing unit. Between the sensor and the flat surface is a focusing system which functions to focus light reflected from such surface onto the sensor. In operation, an object to be scanned is moved through the central opening of the frustoconical surface along the axis of the latter. As the object moves, a light source illuminates successive, circumferentially complete bands of the object at a predetermined location within the space surrounded by the frustoconical surface. Light from the source impinges upon the object from laterally thereof and at an angle to the axis of the frustoconical surface. At least a portion of the impinging light is reflected by the object to the frustoconical surface which, in turn, reflects the light to the flat surface. The flat surface directs the light to the focusing system which forms an image of a respective band on the sensor. The image is analyzed by the processing unit to detect irregularities on the surface of the object.
