Speckleplethysmographic (SPG) imaging yields a much larger signal-to-noise ratio than photoplethysmographic (PPG) imaging, potentially improving noncontact cardiovascular monitoring.
Absolute Event Rate: 0% vs 0%
data suggest SPG has a much larger SNR than PPG, which may prove beneficial for noncontact, wide-field optical monitoring of cardiovascular health.
