A Portable Plug-and-Play Imaging System for Physiological Monitoring

Non-contact physiological monitoring has garnered interest in the research community. However, studies employ different imaging system configuration, including illuminant profile and wavelength, camera type and frame rate, and distance to the skin. In this paper, we propose an easily customizable imaging system for evaluating physiological monitoring parameters. The system’s design allows plug-and-play compatibility with various illumination sources, camera types, lenses, and optical components. Results using one configuration shows the feasibility of spatial blood perfusion analysis using this imaging system, where areas exhibiting clean blood pulsatility can be identified at the surface level.
