This will almost certainly be used for weapons in short order. Currently if you want thermal imaging or very low light capability you have to use very expensive substrates. Being able to use CMOS detectors for MWIR/LWIR would instantly increase available resolutions by an order of magnitude at any given price point, assuming these filters are actually relatively cheap.

I doubt it. It sounds like it has to be “charged” with visible light or something. That means it’s unlikely to be useful some time after sundown, or after being used. I don’t see a military springing for that because it would put constraints on the types of operations they can run unless it adds significant upsides (such as an increase in FOV or something). I do see it being more useful for civilians though, who don’…

Earlier quoted context omitted.

No, if they slap a label on it, it isn't "Don't Use It", it is "Don't even think about exporting this without permission.". It may have been relaxed, but regular IR cameras that we can buy and use here everyday in the US may land you in jail for selling them in eBay and shipping them to a customer in China or Iran. But we can buy, sell, and use them freely.

To say that's a gross oversimplification is putting it mildly.

Question re this: > Although the development of mid-IR (MIR) sources is evolving, a bottleneck con- tinues to be producing low-noise room tem-perature detectors How do these relate to the relatively cheap IR cameras available? Eg, both commercial IR cameras, and military NVGs work at room temperature (Using different technologies). For example, are the devices lamented about in the article high-precision scientific i…
