Image motion photography

Streak cameras operating in the image motion mode are widely used in the photo instrumentation field to measure the velocities of high-velocity projectiles. The larger format cameras are also capable of producing detailed photographs of high-velocity projectiles with virtually no image blur. Although the images produced by these cameras appear to be ordinary photographs, there are major differences that must be understood before any data reduction is undertaken. This report addresses the theory of operating streak cameras in the image motion mode, and the precautions that must be taken during image analysis.
