Abstract

We apply Fourier transform profilometry (FTP) to get the 3D image of a lithic tool. FTP is a fast fringe projection profilometry (FPP) that requires 1 or 2 images to recontruct a 3D profile of the sample. Based on our 3D images, FTP can resolve the features found on the surfaces of the stone tool. We identified the bulging bulb of percussion and rippling patterns on the ventral side. Scars and dorsal ridges were observed on the dorsal side. Thus, developing FTP for lithic imaging may improve the way how lithic tools' features are classified and measured on archaeological sites.
