Abstract: The invention provides an apparatus and method for imaging markings on cartridge cases. It provides for the taking of two images of the cartridge case with light for illumination projected at the cartridge case from two different predetermined angles. In a first version, two different light sources are set at the two different predetermined angles. In a second version, one light source is moved between two different positions to project light at the two different predetermined angles. In a third version, the device holding the cartridge case is rotated between two different positions so light projects at the cartridge case from the two different predetermined angles. In a fourth version, the holding device rotates the cartridge case between two different positions so that light projects at the cartridge case at the two different predetermined angles. In another aspect, the invention provides diffuse light for the taking of the images.

Abstract: The portable spent cartridge casing examination imaging apparatus has a carrying case in which all the necessary components for field imaging of spent cartridge casings are contained securely for transport when the case is closed, and can be solidly assembled in the field for imaging. The case includes a base, a lid which locks in a vertical open position. A spent cartridge casing mounting device is provided for holding the cartridge substantially aligned with a longitudinal axis with the primer surface of the cartridge being substantially perpendicular to the axis, and an imaging system consisting of a cartridge microscope, camera, and light source are solidly interconnected with the mounting device to form a unit which is connected to the lid such that when the lid is open, the unit is substantially vertically disposed, while being at least partially received by the base of the case when the lid is closed for safe storage.
