A low-cost multiwavelength time-domain LED-based optoacoustic system for unmixing absorbers

The study presents a LED-based optoacoustic system for estimating relative absorbers’ concentration in ink - gelatin phantoms. Results support that LED sources present high potential for the development of low-cost optoacoustic spectroscopy systems.
