The biophysical bases of photoplethysmography in the reflected light were investigated by means of simulating the biological object-photoplethysmographic transducer system. The parameters of the system, exerting the most powerful influence on the photoplethysmographic readings, were defined. The program for selecting an optimal design of the fiber-optical++ sensor to solve concrete functional problems was elaborated.
