EM radiation estimation using an automatic probe position recording system coupled to hand scanning

Compared to scanning by hand, traditional robotic scanning to measure or to inject EM near field has advantages and disadvantages. It can scan large area with excellent resolution. However, it is difficult to program the experience of engineers into the robotic system for selecting scan areas, and complex shaped objects are nearly impossible to scan automatically. A CMM (Coordinate Measuring Machine) arm based probe recording system has been developed to add position recording to hand scanning. Applications of the system include documentation, visualization of the field and current distribution.
