GadgetsWe've already seen some attempts to create a tricorder-like device, but this latest crack it at by some researchers at Georgia Tech looks like it could well be the closest to the real thing to date -- if it ever turns into an actual device, that is. The big advance with this one, it seems, is the use of a new mosaic narrowband filter, which includes photosensitive pixel sensors that can observe different wavelengths and allow for multispectral imaging. According to the
