The present disclosure provides devices, systems, and methods for aligning and securing a projectile. A base defining a receptacle for receiving the projectile comprises a self-centering mechanism for aligning a longitudinal axis of the projectile with a reference axis. An upstanding support projects upwardly from the base. A head member extends from the upstanding support, disposed vertically above the base, and has defined therein an opening aligned with the reference axis. A rod member is slidably mounted in the opening, such that a longitudinal axis of the rod member is aligned with the reference axis. A mounting adapter has a first end configured for adhesively retaining the projectile and a second end defining a coupling mechanism selectively mateable with a distal end of the rod member and with an inspection device used for performing inspection of the projectile.

Detection of surface irregularities in coins. Three-dimensional topographic data of at least one surface of a coin, having at least one feature, is acquired and used to determine characteristics of the coin features, based on vector components of normal vectors at various points on the surface of the coin. The feature characteristics are then compared to reference feature characteristics. Based on this comparison, an irregularity indication is provided if differences between the feature characteristics and the reference characteristics are found.

There is described a method and 3D image acquisition system for addressing the specular nature of metallic surfaces in general, and ballistic pieces of evidence in particular, using photometric stereo by identifying and solving a plurality of sets of non-linear equations comprising a diffusive term and a specular term to determine a surface normal vector field N(x,y), and using N(x,y) to determine a 3D topography Z(x,y).
