Course Objective:

The most basic NDT method is VISION ACUITY EXAMINATION. Visual examiners follow procedures that range from simply looking at a part to see if surface imperfections are visible, to using computer controlled camera systems to automatically recognize and measure mostly hidden or remote features of a component.
