The preliminary investigation of imaging photoplethysmographic system
A preliminary CCD camera-based imaging photoplethysmographic (PPG) system is described to detect the blood perfusion in tissue. Attention of imaging photoplethysmography (PPG) is drawn to the potential applications in visualised blood perfusion. The introduction of the fast digital camera inspires the development of imaging PPG which allows the ideally contactless monitoring with larger field of view and different depth of tissue by applying multi-wavelength LEDs. The CCD camera-based spectral imaging PPG system in both transmission mode and reflection mode is constructed to validate the feasibility of this technique. The PPG signal can be derived in both transmission mode and reflection mode, which is obviously different from multi-wavelength LEDs or monitoring at various regions of tissue. The investigation for the system functionality leads to the further development of imaging PPG system and the engineering model for 3-D visualised blood perfusion of tissue.
