Abstract: A slit camera has been designed to permit reliable velocity measurements in low-pressure chambers too small for ballistic pendulums. At two or more viewing ports along a horizontal trajectory, the shadow of the projectile is cast upon a vertical slit. A reduced image of each slit is focused on a film transported in a standard high-speed camera. Timing marks also are put on the film by means of a flashing strobe light. These, together with the measured displacement between projectile images, permit computation of the velocity. The system appears to be the most satisfactory means of attaining accurate hypervelocity measurements. It has been operated with excellent results over a variety of base lengths and gun sizes.
