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