From Head to Toe: Non-Contact Laser Heart Rate and Respiration Rate Detection Under Obstructive Conditions

We demonstrate experimentally laser-based wireless, non-contact sensing of vital physiological signatures including heartbeat and respiration rates, from human subjects without skin access by the laser beam, with nearly arbitrary interrogation locations, from cranium to phalanges.
