Abstract
An inspection system inspects points of interest on an item. A two-axis gimbal holds the item and is controlled to adjust an angle of incidence and angle of approach of a line of sight of an imaging device with respect to the point of interest. A Y-axis actuator adjusts a position of the imaging device along a Y-axis of the item, and an X-axis actuator adjusts a position of the imaging device along an X-axis of the item. A controller controls the gimbal, the Y-axis actuator and the X-axis actuator. Upon selecting a point of interest, angle of incidence, and angle of approach, the imaging device displays and/or captures an image, and the image can be inspected by a human inspector or automated inspection system.
