> Is this also why civilian IR devices are typically slow and/or very low resolution, or alternately very expensive? I haven't followed the professional/consumer market in IR, but as a general statement: The materials systems that you need for IR imaging are different than the CMOS imagers used for visible light (ie, silicon). The IR materials don't have anywhere near the economic or manufacturing scale, so I'd expect that you'll pay more for IR imagers, or will have to accept lower resolution/frame rates.
