Abstract

Photoplethysmographic imaging (PPGI) has gained popularity for
non-intrusive cardiovascular monitoring. However, certain symptoms
(e.g., fever) may not be easily detectable using cardiovascular
biomarkers. Here, we investigate the co-integration of PPGI
and thermal imaging to create a non-contact, widefield, multimodal
physiological monitoring system. To achieve strong PPGI performance,
high-power infrared LED stability was investigated by evaluating
two LED driver boards. Results show that the multimodal
imaging system was able to acquire spatially consistent hemodynamic
pulsatility and heat distributions in a case study. This multimodal
system may lead to improved systemic disease detection
and monitoring.
