Homeland Security Funds LED Light That Blinds, Disorients

katzmeow writes "Ryand Singel's Wired blog notes that Homeland security has developed an LED flashlight that uses 'powerful flashes of light to temporarily blind, disorient and incapacitate people.' The idea is to use it to incapacitate people — 'arrest them' — on airlines, borders, etc. without using traditional weapons. The company's president Bob Lieberman says the tool is perfect for confronting 'border jumpers.' 'You don't want to hurt or kill them, just take them into custody,' says Lieberman. 'With this, they don't need to know English to comply.' The 'light saber' can even be scaled up to bazooka size for subduing crowds."

      Most good welding helmets now use auto-darkening glass. The tint is light enough to see the piece being worked on until the arc is struck, then it darkens enough to protect the eyes.

      I have a relatively cheap one, but it has adjustable darkening, adjustable delay, and goes from light to full dark in 1/10,000th of a second. Some of the better ones have can tell if the light is from an arc or a grinding wheel and adjust their tint accordingly. Pretty cool stuff.

      I;m a good test case for incapacitating light as I am kind of a fan of high powered flashlights, and my eyes are on the photosensitive side. If I'm dark adjusted and I accidentally shine a Surefire M6 at my face I almost immediately become sick to my stomach. My cheap welding helmet can cut that beam down to pretty much nothing though.

    As far as I remember, intrenational laws of war forbid using weapons that blind beople.

    And this WILL blind people. If used from too far away, it won't be efficient so they'll make it more powerful, then used from close range it will make permanent injuries to the eyes. Similar like tasers aren't supposed to kill people, but they do.

    As far as I remember, there was a project in the military to make a similar weapon, using UV laser, but it was scrapped because it was against the international law.

    Of course there are precautions that can be used against this weapon, propper googles should do it, but not everyone will have them.

      As far as I remember, intrenational laws of war forbid using weapons that blind beople.

      Is that permanent and intentional blinding only? Is a specific method of blinding prohibited? Is the prohibition only for using such weapons on soldiers of recognized nations who are signatories themselves? Those questions of course assume that the US still cares enough about the forms of obeying international law to bother looking at such technicalities.

      I'm sure that this thing will permanently blind people, but most pacification weapons can wind up killing or maiming people under a lot of circumstances, so this isn't really any different.

      Is the prohibition only for using such weapons on soldiers of recognized nations who are signatories themselves? As I understand it, things like the Geneva convention are binding on the signatory regardless of who they are fighting against. Wasn't the whole idea to minimise the horrors of war to some degree and to guarantee that the "war crimes" perpetrated in the past would not be perpetrated in the future? On top of that I would have thought that applying a standard to war fighting would ensure that your actions are morally justifiable, if a given action is not justifiable (and you have agreed that is it not by signing a treaty or convention) then the actions of your enemy have no bearing on your own actions, you hold the moral high ground (for what its worth).

      There was a tactic developed by James Maskelyne towards the end of World War II, that allowed the Suez Canal to be defended against German fighter pilots. He basically took a searchlight and placed a set of tin reflectors on top of the search light, which were then made to rotate rapidly. This had the effect of creating rotating cartwheels of dark and bright patches of light in the area around the searchlight. Any pilot who flew above this area would become disorientated due to the mismatch between the perceived motion from the brains centres of balance and the visual cues seen through the aircraft windscreen (optic flow).

      I would guess that this portable system creates enough glare in the eye to make moving bands of light appear on the retina. With a wide enough beam, this will disorientate an entire crowd.

    Actually the opposite.

    Guns can be detected even if they are disguised. It is difficult to hide a chamber, rounds, etc from an X-Ray (not impssible, just difficult). Now this will be trivial to disguise like anything you want starting from a mobile phone and finishing with accessories normally sold in Ann Somers or Agent Provocateur.

    So while the "good" guys (quotes quite intentional actually) may want to have this look like a gun...

    The LED Incapacitator uses a range-finder to measure the distance to a target's eyes and then unleashes continually changing, multi-color light pulses that both blind and disorient the person. How long until this triggers an epileptic seizure in some poor unfortunate - and worse still, would whoever's wielding it be able to tell the difference between the potentially life-threatening seizure and the normal reaction?

    If you make the assumption that it the effect isn't temporary, then no, this isn't a very effective addition to the police arsenal. However, it is the opposite assertion made by this article. I am all for the investigation and innovation of new less-than-lethal methods of subduing suspects. What we have now can be used effectively, but if there's something that can MORE effectively subdue suspects then I'm all for it. For example, if they could create a long range gun that was guaranteed to completely stun someone for five minutes without causing any long term damage, I think that would be a great alternative to shooting them in the head. I'm certain that there are many better ways to peacefully end a situation where a new technology would be the key enabler. And I'm sure you would appreciate it when you're the suspect (guilty or not) and you do something stupid (like wave what looks like a gun around) and the police have three options instead of one before dropping you with their 9mm.

    You first quote wikipedia stating how coherent light can damage eyes. Agreed, by all accounts it does. You then incorrectly infer that this means incoherent light is safe. Wikipedia is wrong or misleading here. In terms of how the beam from a laser interacts with your eye, the fact that it is coherent is irrelevant. What matters is intensity and wavelength. That is what makes lasers dangerous: the beam can be intense and is probably very well collimated. The wavelength determines what parts of the eye may be damaged and whether or not you can see the beam directly.
