Sample Scans

True 3D.

Scans of Coins

Coins provide a useful reference because of their known geometry. Each coin was scanned at approximately 2.2 microns/pixel (rather than the 1.4 microns/pixel we typically use for cartridge casings). The true 3D surface of these coins can be better appreciated in the 3D visualization video (click here).
