Abstract
The apparatus analyzes and compares surfaces of fired bullets. A microscope obtains and amplifies optical signals representative of the characteristics of the surfaces, and the optical signals are converted, first to electrical signals and then to electrical coded digital representations. The coded digital representations are stored in an electronic memory. The coded digital representations of one bullet can then be computer compared to the coded digital representations of another bullet to determine if there is a match between the bullets.
