> You've got Tricorders wrong, they're a generalized non-contact diagnostic tool; someone was working on one but it was just a load of diagnostic devices stuck together. We've got body temperature, and pulse is doable, but not sure what else can really be added to a Tricorder, maybe a tiny mass-spectrometer gets you part way there. In fairness, a tricorder would probably need to be a device capable of gathering data about quantum fields within an extremely local region of space and then analyzing based on known frames of reference and data models, so we're probably a ways off on that one. The harder part of that challenge is building a device capable of analyzing quantum fields in the most abstract sense. But once that's done, even if it's in the form of a massive machine that can only analyze spacetime in a small chamber, even if that machine is rooms-big, the race to the first tricorder begins. (I could be completely off-base with my comment on analyzing quantum fields. I'm not at all an expert.)
