Temperature configurable light-emitting diode (LED) array as a reconstructive spectrometer

Published in Applied Physics Letters, 129(7), 073305, 2026

This work presents a low-cost approach to reconstructive spectrometry using arrays of commercial light-emitting diodes operated in photovoltaic mode. Temperature provides an additional tuning parameter to improve spectral reconstruction, offering a route toward accessible, portable spectrometers.
