N2 - Plasma optical emission spectral imaging is critical for the development of chemical analysis applications
and plasma diagnostics. Nevertheless, typical techniques require array detectors that can be very
expensive or pixel-to-pixel rastering approaches that are highly time-consuming. Further, the acquired
image files are compressed to keep data manageable, which can be achieved without loss of critical
information, thus showing the sparsity of the data. A fairly recent paradigm in sampling, compressed
sensing (CS), allows performing compression during acquisition which results in a more efficient use of
experimental resources. As such, CS systems can be much faster, cost-effective, or even provide better
resolution or throughput. In this study, a CS spectral imaging system, featuring a single-sensor and
a variable encoding mask, is designed and implemented for plasma optical emission spectroscopy. The
performance, based on PSNR and spatial resolution, is characterized as a function o
