Influence of sensor design and optical properties of tissue on the photoplethysmographic signal

Abstrakt

Photopletysmography and an associated technique called pulse oximetry are still explored due to the expectations that they give a lot of information about the state of the patient and, also, due to the fact that they are non invasive. Knowledge about the impact of various parameters on the measured signal leads to a faster and a more reliable way of analyzing measurement results and finding the dependencies between the involved factors. This study is an overview, where different factors which have an impact on measuring the PPG signal are presented. The factors related to the sensor structures, namely: wavelength, distance between the light source and the detector, mode of work: transmissive or reflective, are presented together with the light interactions with tissue described by absorption and scattering coefficients, the refractive index and the anisotropy factor.
