  • The apache helicopter, more specifically the MTS imaging system you're talking about, uses a completely different type of imager that requires cryogenic cooling. It's because the imager is kept at such low temperatures that the scan mirror has to be there. This mirror does nothing to improve the image or field of view which is ultimately determined by the optics. It simply breaks up the image to limit the imager's exposure to photons in order to limit local heating that causes the bleeding effect you're talking about. Uncooled systems don't suffer from this problem since they are essentially the same as a traditional digital image sensor, but the downside is they have significantly reduced thermal resolution. I used to test the MTS and it's thermal imaging capabilities are light years better than even the most expensive FLiR systems.

No public wish lists :(
