| Paper compares the performance of an ICCD and Ocean Optics spectrometer/detection system. ICCD results are here for aluminium alloys, here for copper alloys , Ocean Optic are at here for aluminium alloys and here for copper alloys. Experiments were performed under common conditions, and then conditions optimised for each detector The authors note that their Ocean Optics spectrometer had a 250ns timing jitter that has been fixed on subsequent models | |||||
