Laser camera reads heartbeat from a distance

Researchers at Glasgow University have developed a laser camera that uses AI and quantum technologies to read a person's heartbeat from a distance. The system could be used in shopping malls or homes to monitor health parameters, including blood pressure and gait changes. The technology can detect irregularities and is more accurate than traditional stethoscopes. The team has established a start-up company, LightHearted AI, to further develop the devices.
