Abstract (en)

[origin: WO9512810A1] A method for checking the surface condition of one side (2) of a solid (1) to detect any shape defects that may be present therein, and a device therefor, are disclosed. The side to be checked is observed, for example, by imaging with a wide-angle video camera (3) and a narrow-angle video camera (4) and the size of the detected defects is measured by means of an opto-electronic sensor (11). The device is useful for operator checking or automatic checking.
