here are first results of a new setup project I´m developing with Godehardt for medical research.
The task is to scan small medical stuff in formaldehyd. The final object will be only about 15mm, swimming and only fixed to the top. So the basin cann´t be put on the turntable and has to stay stationary (to avoid streaming of the liquid) while the cam/projector combo orbits around. The next problem will be the subsurface scattering of the organic material. So I decided to try the SL way before going to try a microline laser. I had good results using the UofK SL scanner on similar stuff, but IMO its calibration is rather trcky and not as robust as DAVID ´s is.
For test purposes I used a plastic torso of 27mm. I fixed it with some putty (the waves in it are my fingerprints). The cam is besides the projector and twisted 90° around its viewing axis, for its projected stripes are vertical on a horizontal oriented corner to calibrate and reference the scans. This twisting was necessary because of the upper water surface and the bottom of the basin. With a normally oriented setup I got problems with the depth of the basin and/or reflections on the surfaces....
hoo, holla Gunter this is great do You know what this could give in posibilities ? all those collections in universities (and musea) that could be evaluated and preserved in an other way I hope You'l continue this study may the "force" be with You Luc
