Night Vision Googles: Always wanted to know

Recommended Posts

I thought this would be a good place to ask. So what happens if you're wearing night vision equipment and all of a sudden a flare or other bright source of light appears?

Thanks

deer in the headlights I believe.  One of the things the Mahdi used to do in Sadr city is set up lights on generators and if the US raided at night they'd kick on the lights to take away the night vision advantage.

That is sometime ago and that may have changed since.

Well, with Google's new night vision capabilities I won't need to. I can finally retire my glow-in-the-dark banana hammock.

Poor Sequoia, what one missed consonant can do to a thread. It was a vowel movement of epic proportions.

Well he's obviously worried about the dark web.

Damn, can't edit titles.

Also can you use night vision googles in the dessert?

 

As long as you keep them out of the whipped cream.

P.S. Now he's just trolling us.

But seriously, I'm guessing the wearer would be blinded for some time right?


The more advanced image-intensification systems have "auto-gating": 

"This maintains the optimum performance of the I² tube, continuously revealing mission critical details, safeguarding the I² tube from additional damage and protecting the user from temporary blindness. The benefits of ATG can easily be seen not only during day-night-day transitions, but also under dynamic lighting conditions when rapidly changing from low light to high light conditions (above 1 lx), such as sudden illumination of dark room. A typical advantage of ATG is best felt when using a weapon sight which experiences a flame burst during shooting (see figures below showing pictures taken at the impact zone of a dropped bomb). ATG would reduce the temporary blindness that a standard BSP tube would introduce, allowing them to continuously maintain “eyes on target”."

Googling around, it looks like the US PVS-14 is auto-gated.

If the light is hitting the lens directly it'll just flare up and you won't be able to see much. That's all. You don't go blind or anything. The eye that isn't covered(in the case of PVS-14s) will adjust pretty quick, but it is quite a shock.

As long as there is some form of light (IR flood, star light, or moon light) you can see.

Driving with them on sucks, fortunately I was a gunner and didn't do much night driving.

The dessert comment, as Mord noted, was just a troll reference to another thread where someone confused desert with dessert, but thanks for the answers. ;)

Yea I caught onto that after I posted and I'm too lazy to edit/delete it.

Oh well.
