Hyperspectral imaging is a method that captures a far greater amount of the electromagnetic spectrum than a regular photograph. This makes it ideal for a variety of uses, from night vision to identifying mineral deposits from afar, but the problem is that hyperspectral sensors don't come cheap. However, some intrepid imaging scientists have come up with a way to turn your DSLR into a hyperspectral camera using stock SLR glass, a gel diffraction filter, PVC pipe, duct tape, some serious ingenuity and plenty of elbow grease. Thusly did they build a (relatively) cheap-as-chips imaging spectrometer that can de
