From: Non-contact Quantification of Jugular Venous Pulse Waveforms from Skin Displacements
The experimental set-up used to record videos from the JV pulsation area. A laser displacement sensor was used to validate the displacement measurements of our method. The camera and the laser displacement measurement sensor were placed at approximately 45° with respect to the skin surface, and perpendicular to each other to avoid perspective distortion effects in the camera view.
