Abstract
A striation monitor and display system (10) is provided which includes a positional location mechanism (20) for locating a substantially cylindrically contoured object such as a bullet (14). The bullet or object (14) is inserted within a collet mechanism (48) mounted above a cup member (44) containing a compliant matrix (46). A portion of the object (14) is inserted along an axis line (24) of the rotating cup (44). A line scan camera (62) is focused on a section of the object (14) and frame speed is synchronized with the rotation of the rotating cup (44). Synchronization is accomplished by a closed feedback loop between a motor/encoder integral combination (58/60) and a processor system (72) for maintaining synchronization between images photographed by line scan camera (62) and rotational speed of motor (58).
