Well who knows what the world of optics will come up with next? Might still be time for a request to Santa.

Some of the geek comments miss the point: this is a LPI (low probablity of intercept) system that can be used at short range and with much higher data rates than radio systems with a lower chance of detection.

I rather suspect they use an IR laser too. Not going to use a visible one now are we

And of course they're going to be encrypted on the battlefield. Everything is today.

They quote 1.6miles (2.5km) which seems like a typical military use distance. IIRC military 7x50 spec calls for IDing a man at 3000m - that's about a 2 arc minute target (about 15 "pixels" of resolution tall).

On a more bird-related topic ... it makes one wonder if one could make a small IR signaling bird tag. But then again colored bands work quite well over line of sight distances with a spotter or a bin though a strobe might give quicker automated ID

Hmm, I wonder how much these puppies usually go for?
