Abstract:
Extreme-Light Nuclear Physics (ELI-NP) facility in Romania is part of the pan-European distributed facility that addresses laser physics research with emphasis in the field of nuclear physics (in Romania), secondary radiation sources (in the Czech Republic) and attosecond light science (in Hungary). At ELI-NP, experiments will be carried out by using a High-Power Laser System (HPLS) delivered by Thales Company. Within the HPLS, cameras acquire images at different frequencies (from 10 frames per second to 1 frame per minute). They contribute to more than 90% of the data produced each day (around 700 gigabytes). These data are stored in Hierarchical Data Format 5 (HDF5) files on different servers located in the HPLS network. Thus, in this paper, we aim at presenting how digital image processing techniques applied on images can be used to reduce the amount of data that should be stored at the ELI-NP data center. The ensemble of these techniques were grouped and structured in order to form a laser beam detection algorithm. The algorithm was tested on different laser beam intensity profiles (Near-Field and Far-Field). As a conclusion, this paper offers a perspective upon the future development of testing quantitatively the algorithm and improving it.
