Can someone ELI5 the vibration isolation [0] part of it? I kind of get what he's doing, but would appreciate some analogy if it makes sense to make an analogy.

  In a nutshell: the vibrations that affect the imaging are pretty high frequency. So to get rid of them he has isolated his whole setup in such a way that if there is a vibration it will be well under the lower cut-off frequency that is part of the measurements. So the whole apparatus may go up or down but that won't affect the measurements. If the whole thing would not be isolated then the rumble from the tires of a passing car or a jet flying over would utterly ruin the measurements. Especially the vibration damping is nicely done, it is zero contact and has the effect of stopping any beginning oscillation in its tracks.

  Imagine painting with a paintbrush while standing on a jumping castle with 5 jumping children. If you have no vibration isolation, it is nearly impossible to draw a very thin and straight line. (Maybe a bit exaggerated, the vibration analogy is a bit weaker in reality)

  Incidentally all of the techniques listed there are used for suspensions in LIGO, Virgo and other ground-based gravitational wave detectors, where the problem is the same: stop seismic noise from moving the object under test.
