…techniques. CCD Array Camera Diagnostics CCD array camera-based diagnostics use an array of sensor pixels to measure the intensity over the face of the entire laser beam simultaneously. This allows them to capture data from pulsed lasers and display the data in 2D contour plots and 3D views. The pixels are…
