Paper Abstract

A novel miniaturized near-infrared spectrometer readily mountable to wearable devices for continuous monitoring of individual’s key bio-markers was proposed. Spectrum is measured by sequential illuminations with LED’s, having independent spectrum profiles and a continuous detection of light radiations from the skin tissue with a single cell PD. Based on Tikhonov regularization with singular value decomposition, a spectrum resolution less than 10nm was reconstructed based on experimentally measured LED profiles. A prototype covering first overtone band (1500-1800nm) where bio-markers have pronounced absorption peaks was fabricated and verified of its performance. Reconstructed spectrum shows that the novel concept of miniaturized spectrometer is valid.
