Typically, cameras in a solar wafer edge chip detection system are set-up to provide either a top-view or a side-view of a wafer. The top-view camera set-up is found in most existing systems. This set-up as illustrated in Fig. 2a, places the camera on the top of the wafer, allowing the top surface of the wafer to be captured. ...
