Sounds like (slightly exaggerated) VR sickness symptoms, e.g. when there's too much latency between head movement and vision updates. Some people are more sensitive to this than others.
These new ones would be wild, I’ll see if I can get a demo this year somewhere.
I don’t get any motion sickness with Gen3 IIT’s even moving fast, but with digital systems there’s a latency in refresh rate that becomes very disorienting.
The thermal part of the combined system is digital - in the units I’ve looked at, the image from the thermal is “projected” into the IIT’s lens. So while the image from the IIT alone is lag free, the thermal overlay does have lag and can mess you up a bit.
I’ve played with some older kit that was somewhere around 14hz or so and was fucking awful, felt like being ill after walking around in them!
Basically it said infrared goggles use digital processing, so there's at least one frame of lag for every image, which can cause those issues. Image intensifying googles are totally analog so there's no lag to avoid that issue.
Well, 24 fps vs 120 fps would technically matter, to the point where at a high enough frame rate you could not possibly tell the difference; I suspect it's more like 48 fps (if it's a constant 48 fps) than 120 *
The give-and-take relationship between this technology and video games is ... something.
I can’t understate how fucking awesome the technology is, even the stuff available in civilian market.
In the US it’s possible to get really nice L3Harris Gen3 tubes, whereas in Europe you are more likely to find Photonis Echo or similar - which are really nice.
There’s the older school green phosphor tubes, and more modern white phosphor tubes - the WP ones are better in terms of contrast, and IMO easier on the eyes.
The set I have the most time on uses Gen3 WP Photonis Echo tubes, and is really nice, but I’m told it doesn’t hold up great compared to the ones available in the US.
There’s some Chinese tubes on the market now that are supposedly rather good, but I’ve not played with those.
I wonder if they reverse engineered the stuff we left behind in Afghanistan.
While the general science behind Gen3 NVG is pretty well known, having a few sets in hand would have massively sped up development, and there’s now a couple of suppliers knocking out really quite respectable tubes.
Even the chassis for them with a “install your own IIT” is stupid expensive, and 3DP versions of the chassis just aren’t there yet.
Tan is useful because it turns out it's a element of both temperature and arid environments.
*There are other considerations of course, reflectivity (including in the NIR spectrum) is a much larger concern in low light conditions for instance.
Do you mean, if they would place an order for +1 unit today, what would they be invoiced for that specific unit? This question is quite irrelevant, because they don't order them one by one.
Or, what is the total cost of the project, averaged out onto each unit that has currently been ordered and delivered? Or just ordered? Or planned to be ordered? Each question has a vastly different answer.
Or, what is the projected final average cost per unit, once the device has been deprecated in favor of the next generation?
These projects always consist of the price of the hardware (which changes), the developmental costs, the internal costs of the staffers in the army (air force? pentagon?) working on the project, maintenance of the device, training for the device, repairs of broken devices, and so forth.
There are follow up orders, numbers are less firm on that one.
Which cameras cost less than 39k that are manufactured at less than 2500 per year?
