Everyone has a heartbeat with a unique auditory signature. A new device developed for U.S. Special Forces can be used to tell them apart similar to irises or fingerprints even at a distance.
A new device, developed for the Pentagon after US Special Forces requested it, can identify people without seeing their face: instead it detects their unique cardiac signature with an infrared laser. While it works at 200 meters (219 yards), longer distances could be possible with a better laser. “I don’t want to say you could do it from space,” says Steward Remaly, of the Pentagon’s Combatting [sic] Terrorism Technical Support Office, “but longer ranges should be possible.”
[...]the new device, called Jetson uses laser vibrometry to detect surface vibrations the heartbeat causes on skin, clothing, or jackets (though it is not effective through very heavy clothing such as thick winter coats).
Cardiac signatures are already used for security identification. The Canadian company Nymi has developed a wrist-worn pulse sensor as an alternative to fingerprint identification. The technology has been trialed by the Halifax building society in the UK.
Jetson extends this approach by adapting an off-the shelf device that is usually used to check vibration from a distance in structures such as wind turbines. For Jetson, a special gimbal was added so that an invisible, quarter-size laser spot could be kept on a target. It takes about 30 seconds to get a good return, so at present the device is only effective where the subject is sitting or standing.
The developers of the technology indicate that this could likely also be adjusted to scan remotely for heart issues such as arrythmias.

I was joking, years ago, when I posted stuff about the government's invisible brain lasers.
The joke was about how to construct tin foil hats, using two layers of foil, to build up a resonance effect at exactly twice the frequency of the government's invisible brain lasers.
But now, this article? Seriously?

Maybe instead it should be worn around the chest? But could the cardiac acoustics be picked up from wrist veins, neck veins, etc?

Brain waves might leak out through your face - keep it on, but modify it to ensure it covers your whole head, to the neck.
Get a separate foil jacket for this heart device.

Great, your subject can be a mile away (with a better laser), but... you've got to get him to sit still with his heart exposed for 30 seconds - likely longer, if they're being honest about real world conditions and especially non-cooperating subjects.
I'm thinking that most bulletproof vests will effectively mask this tech, so...
On the other hand, literally, you could put somebody's hand on a table and get similar information from pulse oximetry style reading of the blood pulsations in the visible arteries. This would both ID your subject at the immigration desk, and also take their pulse rate which certainly could be a flag for heavy stress...

I think a more real world application is to determine whether that's a particular foreign leader or his double, before taking the shot.

If one of your agents is being held hostage under primitive conditions, he's not wearing a vest and he's probably got nothing better to do than sit still most of the time. You'll use this technology in order to figure out who *not* to shoot.

Imagine talking to your parents after they're parched from work, or have just worken up, or have been crying. They'd sound far from their baseline but be easily distinguishable.

Laser vibrometry has been a thing in the tech industry for a long time, used to determine the vibrations of bond-heads on wirebonders, for example, for calibration purposes. Now laser interferometry is used because it's cheaper.

I could see there being a market for a pendant that issued a false heart beat, maybe variable. I'd love to have the heart beat of a humming bird or on the opposite end the lethargic heart rate of a hibernating bear or an alligator at the bottom of a bayou. Match that with shoes that had variable inflatable soles that altered you walk, and a pair of glass that projected a field that distorted the planes of your face via infrared or laser light.

I can also see a market for new, improved, deely boppers where the globes are clusters of diodes sensitive to most of the common laser wavelengths, given the typical spacing and height above your head, this should give almost 360 degree coverage, including against pings from drones/above...
maybe get them to make a 'bloop bloop whortle bloop' noise when they detect that you've been pinged...

The drone circles overhead, high enough to be invisible and silent. The laser, unseen autonomously scans each one of the men. Network analysis says that he should be here. The mac address of the burner he used an hour ago is here. There he is. The missile rattles off the rail. Now he's not here anymore. A line in a spreadsheet turns red. A pie chart is updated.
