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

Abstract

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.
