The use of photoconductive cells in photoplethysmography
Medical & Biological Engineering, 1973Photoplethysmography (p.h.p.l.) is a noninvasive method of monitoring changes in peripheral blood volume. The method consists of illuminating the skin with a light flux, and detecting transmitted or backscattered light from the vascular bed by a photosensor.

Pain recognition with camera photoplethysmography
2017 Seventh International Conference on Image Processing Theory, Tools and Applications (IPTA), 2017In the last years a lot of effort was made in predicting the heart rate of a participant with remote Photo-plethysmography (rPPG) from the video channel but only few authors used it as a biosignal for classification of e.g. stress. In this work, we present the rPPG signal as a new modality for pain classification and evaluate the benefit of the three ...

An overview of non-contact photoplethysmography
2017 25th Signal Processing and Communications Applications Conference (SIU), 2017Photoplethysmography (PPG) is a method which is used to extract physiological parameters such as heart pulse rate, respirotary rate, and their variation with respect to time by optically measuring the blood volume change in the tissue. Photoplethysmography methods can be categorized into two groups: contact and non-contact.
