What exactly is the difference between Fast and High Accuracy?
- number of samples?
- resolution of the scan?
- number of points in the point cloud
- or maybe it’s just a preset for the Point cloud fusing tool to give more o less detailed point cloud?

Only for the POP 2 (the original POP doesn’t give you this choice), High Accuracy is the 0.1mm pitch and Fast is the original 0.3mm pitch.

Ok, so the scanning resolution then. Thanks 
Not so fast , the resolution depends of the meshing settings , in Revo Scan the maximum is 6 in Revo Studio the maximum is 7 what is 75% higher than 6 . However higher resolution don’t means you will get more details.
Higher accuracy means how far the points are from each other , the maximum accuracy for cloud point is 0.1mm in the Fast mode the accuracy starts at maximum 0.3mm , some claims high accuracy can be even at 0.5mm as long you fuse the cloud point in Revo Studio or other programs as Revo Scan offers fusion at 0.1mm only .
so this is about the Accuracy of the scanned model features / details to be exactly.
So if you want more details , always scan using Higher Accuracy and fuse the cloud point and mesh it in Revo Studio. Remember to remove overlapped points before meshing it .
Exacly - I meant the resolution of the point cloud, not the generated mesh
It is spatial resolution aka point cloud density aka point cloud accuracy , all means the same
