ABSTRACT:
A system and method for detecting defects in a material in a liquid bath, the system including a light that illuminates the material through the liquid bath, at least one camera with a view of the material through the liquid bath, and a digital processor in communication with the at least one camera. The at least one camera transmits image data to the digital processor and the digital processor analyzes the image data to identify defects in the material. In an embodiment of the invention, the system includes an anti-turbulence interface through which the at least one camera views the material.
