Invasive and Non-Invasive Observation of Occluded Fast Transient Events: Computational Tools

نویسندگان

چکیده

Industrial processes involving thermal plasma such as cutting, welding, laser machining with ultra-short pulses (nonequilibrium conditions), high temperature melting using electrical discharge or ion-beams, etc., generate non-repeatable fast transient events which can reveal valuable information about the processes. In industrial environments containing and radiation, it is often difficult to install conventional lens-based imaging windows components observe events. this study, we compare requirements performances invasive non-invasive modes when a event occluded by metal window consisting of numerous holes punched through it. Simulation studies were carried out for different types patterns, reconstructed both compared. Sparks generated rapid behind thousands through-holes time sequence was recorded high-speed camera. The without spatio-spectral point spread functions Commented MATLAB codes are provided reconstruction.
