I’ll also note that I’ve been involved with the field of hyperspectral imaging from not long after the technology trigger.  I’d say the field is currently on the Slope of Enlightenment.   (Sorry the ‘hyperspectral imaging’ link isn’t very good.  The Wikipedia entry contains a hefty dose of stealth advertising and I couldn’t find a good academic link which describes the field for non-specialists.  Most sites seems to presume you already know what it is.)
