It is impossible to estimate arterial oxygen saturation (i.e., SpO2) for individuals by using conventional approaches unless the given sensor of the pulse oximeter is attached to an individual’s finger. This study introduces a novel method to solve this problem. This study has focused on realizing SpO2 measurements by using non-contact space measurements, and the success of the approach is validated through experiments. Finally, despite a few problems including the susceptibility of the proposed approach to other light interference, the study offers an initial method to utilize laser wavelengths for the fore-mentioned purposes. As the characteristic of elderly individuals involves the hardening of the fingertips’ skin, it is difficult for the light of a probe to enter the same. Therefore this study can be applied to medical care, elder care, and other related fields. .Additionally, there are cases that symptoms are unmeasurable. The light receiving property to other light interference in space constitutes a problem for the fore-mentioned method.
