This is clearly a new and highly interesting field of civil application.

Do they use POET? No, not yet, but - this will be one further application, a low cost one-chip IR spectro you can easily build inside a smartphone. In deed, soon we will have real tricorders, and we already now own the right technology for that! POET!
