New laser technology can read heartbeat recognition target identity from two hundred meters away.
This technique uses an infrared laser to read a person's heart signal. Although the technology is far less obvious than fingerprints or face recognition, people's heartbeats have a unique contour that makes it one of the most useful biometrics available as a special way to identify someone.
At present, the effective detection range of this identification technology is about 200 meters. If the technical adjustment is made, the detection range can be further expanded. At present, it is impossible to detect someone's heartbeat data from space, but a longer distance is possible.
The heartbeat mode is collected by detecting changes in infrared light caused by a person's blood flow. It is not only highly accurate, but has an accuracy of about 95-98% and is very versatile. Unlike facial recognition technology, laser-detected heartbeats can penetrate clothing for information collection, while facial recognition requires a clear view of someone's face.
This method requires a beam of stealth laser to aim at the target for about 30 seconds to get enough readings, which means that the technology can only be effectively applied to people standing still. As for applications, the technology can observe the ground through drones. The rebels’ heartbeats identify their identity.
However, as with any biometric database, the biggest obstacle to achieving this use is to generate a large enough database cross-reference and cross-reference, and the technology may be applied to more civilian areas, such as hospitals, where doctors can monitor The patient's blood flows without having to apply medical equipment to the patient.
