In the last few years, LIBS has become an established technique for assessment of elemental concentrations in various sample types. However, many applications knowledge about overall composition is not sufficient. addition, detailed information distribution within a heterogeneous needed. great interest imaging studies, since this allows to associate obtained with spatial coordinates investigate...

The SuperCam instrument on the Perseverance Mars 2020 rover uses a pulsed 1064 nm laser to ablate targets at distance and conduct induced breakdown spectroscopy (LIBS) by analyzing light from resulting plasma. LIBS spectra are preprocessed remove ambient light, noise, continuum signal present in observations. Prior quantification, masked noisier spectrometer regions normalized minimize fluctuat...

Abstract This work addresses a bottleneck usually encountered in the processing of large amounts LIBS data. It shows how fitting emission lines typical spectrum can be automated. is done by exploiting second derivative to obtain reasonable parameter estimates that, together with divide and conquer approach, used fit numbers crowded without user intervention executed within timeframe. As demonst...
