Integrating Sphere Finger-Photoplethysmography: Preliminary Investigation towards Practical Non-Invasive Measurement of Blood Constituents
The aim of this study was to compare conventional photoplethysmography (PPG) in a finger with PPG using an integrating sphere ((IS)PPG) to enhance scattered light collection. Two representative wavelengths were used; 1160 nm, a window through the absorption spectra of water and alcohol, and 1600 nm...
