I'd like to interrogate those ideas, if you don't mind? I'm truly curious here. Somewhat skeptical from the impression my reading has given me, but I don't mean to be hostile.
The initial testing is all very well, and I have no reason to expect it's at all ineffective, but I imagine it would be more interesting to look at the consequences of wear/weathering over time.
I suppose my biggest question is the mechanism by which those (fixed and personal) detectors work. I know that the aerial solutions work via lidar, and I expect satellite similarly looks for absorption in particular wavelengths.
