MicroCT Rotating Target and a Holiday Fruit Cake
In the Sustainable Archaeology Ancient Images Lab, we've been performing proof of concept tests using the rotating target on the microCT. The rotating target enables the user to "up" the flux (amount of power) that can be delivered to the target, without degrading the spot size - essentially allowing for faster scanning without compromising the excellent resolution of the machine. This give us the ability to greatly increase the amount of power we can use in a scan, allowing us to scan very dense objects, including meteorites, or, holiday fruit cake!

I would like to trade information on tweaks and work-arounds for 3-D scanner issues. We have purchased a next-engine 3D scanner, but have problems with sharp edges (I would have liked to see a 3-D Adobe file of the small projectile point you have a plan view of, to see if your system dealt well with this), find out what software you are using to do things like manually add points to the scanned cloud that will then be used in mesh, transforms to translate the files to a format Adobe will use for easy dissemination, etc etc.

Hi Morley, great to hear from you. We're using a 3D3 white-light scanning system with some post processing using Geomagic. The edges that aren't captured via the scanner are filled using Geo. We keep these edge gaps to a minimum by taking as many scans as feasible.
