However, you have to consider what's considered quite adequate today.
Not many precise measurements are made at all, and those are "by guess and by golly" as they say, with roundoff done mentally, and so on. Further, adjustments,.... Sure, but why design a system that guarantees more manual fix-ups are necessary ? If you are going to the trouble to collect contour/pressure info, it seems not a good idea to limit precision by design. I'm persuaded that a cone-shaped "virtual socket" with a length-adjustable framework of some sort, yet to be devised, would serve as the "track" on which this thing would travel. I expect the design of the physical mechanism might be a bit tricky. That's TBD, as yet. I first thought of a 'U' track, then figured a large 'O' track might be more useful, as it allows two scan axis for 3D Contours. A limb can go 'thru the hole' for scan, or in the same plane as the track. |
