Title: SURFACE FEATURES BY AZIMUTHAL ANGLE
Abstract:
Provided herein is an apparatus, including a photon emitting means configured to emit photons onto a surface of an article at a number of azimuthal angles; and a processing means configured to process photon-detector-array signals corresponding to photons scattered from surface features of the article and generate one or more surface features maps for the article from the photon-detector-array signals corresponding to the photons scattered from the surface features of the article.
