    Abstract

    In this paper a non-contact pulse oximetry imaging system is described. The system utilises a CMOS digital camera and near infrared (NIR) light emitting diodes operating in a reflection mode to simultaneously capture photoplethysmograph (PPG) signals at two wavelengths. The Modified Beer-Lambert Law is used to extrapolate tissue oxygenation from the PPG signals. Attention is drawn to the system’s potential in applications such as the assessment and management of wounds.
