Why the study?
High-efficiency acquisition of transient image data in non-contact vital signs monitoring by image photoplethysmography remains challenging and generally requires complicated data processing.
A snapshot multispectral imager provides a novel, rapid method for non-contact measurement of facial blood oxygen saturation.
Rapid non-contact SpO2 measurement is feasible via snapshot multispectral IPPG; leaves open prospective clinical validation before diagnostic use.
Blood oxygen saturation measuring is crucial for the diagnosis of disease severity. Despite the great efforts in non-contact vital signs monitoring by image photoplethysmography (IPPG) technology, the high-efficiency acquisition of transient image data is still challenging and generally requires complicated data processing processes. In this paper, we demonstrated a novel method for rapid measurement of blood oxygen saturation. A snapshot multispectral imager was employed in the proposed solution to transiently capture changes in spectral image information from facial tissue skin.
