DEVICE FOR THE DETECTION OF FAULTS ON A WORKPIECE

摘要

A device automatically reads indications of flaws in a piece using the sweating method. An ultraviolet beam illuminates the piece to be checked after successive reflections on a separating mirror and on two oscillating mirrors for sweeping. The beam reemitted parallel to the incident beam traverses the separating mirror and is received by a detector, the output information of which is transmitted to a data processing unit which also receives information on the position of the oscillating mirror over a different path.
