I've heard the javelin missile launchers have been great in ukraine because they can double as night / thermal vision. This concept seems similar to me. Never been on a battlefield but I guess it seems dubious that most modern soldiers don't have some form of digital aid?
- int_19h 4y agoNight vision is not digital, usually (digital NV exists, but it's not as good at amplifying as gen3 analog NV). Thermal has digital screens, but it's far less widespread than NV.
- spywaregorilla 4y agoWhy is that? I would assume digital night vision would be vastly superior catching a lot of edge cases like bright likes becoming blinding?
- int_19h 4y agoI don't know the specifics when it comes to the physics of it, but analog NV amplification simply has more sensitivity than digital image sensors. Of course, you can still analog-amplify an image onto a camera sensor for further digital processing, but I don't think that's common. The particular case that you describe - automatically adjusting to ambient light - is handled adequately by analog circuits; this is called "auto-gating", and is pretty much standard nowadays.
