    Active camouflage need only require that you emit the same light passing through. If you have a versatile enough emitter, you could absorb some light to observe and emit the rest on the other side. Thus you can have a perfect active cloak PLUS be able to observe as well. Net energy has to be around zero, so you'll be burning power to run it, but it's better than blindness.
