A proof of concept demonstration of the automated laser removal of rock from a fossil using 3D X-ray tomography data

Laser removal of rock from around a fossil using 3D data was demonstrated was the first time. This proof of concept combines the power of two technologies: X-ray micro-computed tomography scanning and programmable scanning laser ablation. This simple demonstration holds promise for the semi-automate...

Description
Summary:Laser removal of rock from around a fossil using 3D data was demonstrated was the first time. This proof of concept combines the power of two technologies: X-ray micro-computed tomography scanning and programmable scanning laser ablation. This simple demonstration holds promise for the semi-automated and entirely safe laser removal of bulk material from around precious fossils. •Automated and safe laser removal of rock from around a fossil is demonstrated.•X-ray computed tomography is combined with programmable scanning laser ablation.•Laser fossil preparation is hereby demonstrated on a simple test example.
