Fired cartridge examination method and imaging apparatus

The device, comprising: aA fixing base, the cartridge case percussion the surface cover is arranged along the shaft ordinate the cartridge case is formed with a clamp of ordinate shaft and; deviceA cartridge case monitoring lens, wherein the optical shaft is roughly parallel to the ordinate shaft; A focus mechanism, a focusing the lens, wherein a pin on the surface and formed on tail of the percussion and surface of percussion cover; the surfaceAn axisymmetric light source, the wall axisymmetric light to the ordinate shaft encircles the tail the surface and a pin on the surface. The tail end surface and a pin mark's image can be used for using the comparative tension; the cartridge case angle direction of with a clamping element supporting device on two sides of nothing to set. The parsing, when cartridge case the first and second and a computer of each other is relatively, thus the rubber rotating first and second image maximal correlative value.
