Using light sensing to acquire SpO2 biological information via a non-contact approach

Abstract

Using conventional approaches to estimating arterial oxygen saturation (i.e., SpO2) for individuals, it was impossible to measure unless the given sensor of the pulse oximeter was attached to the finger. In this study, we attempted to realize successful SpO2 measurements using non-contact space measurements and succeeded in our experiments. Our work can be used for medical care, elder care, and other related fields. Finally, even though we observed some problems in that our approach was susceptible to other light interference, we offer our work as a first method using the laser wavelength for these purposes.
