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
