The Pentagon has a laser that can detect people from a distance by reading their heartbeat

According to the MIT Technology Review, a laser has been developed for the Pentagon that can read the signatures of a unique human heartbeat; it was later requested by US Special Forces. The code-named Jetson, the device is still in the prototype stage but is already about 200 meters (656 feet) away capable of reading heartbeats even through human clothing.
You can change your face with plastic surgery or even burn your fingerprints, but you will fight to avoid detection once the US military begins deploying its latest surveillance gadget.

Each person has a completely unique and unique heartbeat profile, making it a much more reliable biometric for pinpointing individuals. Like other personal certificates such as the face, fingerprints and irises are usually used as recognition, but errors in identifying the meaning of the match between individuals can occur. It can be used to detect people from any distance and from any angle which is more convenient than the current method which requires a clear view of a person’s face or access to their fingers. Jetson uses a technique called laser vibrometry to detect subtle changes in the reflection of ultraviolet light as a
A person’s skin and clothing carry their heartbeat with them. He further claimed that the current prototype has about 95 percent accuracy, speaking at MIT, Steward Remaly of the Pentagon’s Office for Counterterrorism Technical Assistance said, I don’t mean that you can do it from space … but longer fields should be possible.”

Currently, the laser takes about 30 seconds to create a text, meaning it can only be used on static subjects. Perhaps the biggest hurdle is the fact that a database of cardiac signatures really needs to be created so that texts can be cross-referenced and identified. However, while military officials hope that one day
Jetson will be used to identify insurgents from drones; a few technical issues need to be uncovered before the technology can be installed. If this new remote monitoring method is always used, this will certainly be met with a lot of privacy concerns, considering the possibility of people spying from afar. Plus on the side, you no longer need to immerse your fingers in acid to avoid detection.
