It operates on a FireWire bus and multiple scanners can be chained for wide coverage. The custom software processes the images after capture, producing a 3D model without holes or spikes-- amazing accuracy and low scan time (though post processing from 2 units took maybe 15s). Multiple simultaneous datasets are merged automatically based on units' calibrated relative positions.
Here's a medical installation with four scan heads built into the console-- scan heads themselves looked to be ~3"x15"x12" (WxHxD).
