Show Super Speed Pictures Show Bullet in Flight r: iVr J'- . I I' I I 'M Extremely rapid photographs, taken at one-millionth of a second, were demonstrated recently by Dr. F. W. Godwin of the Armour Institute of Technology. The process of photographing: a bullet in flight (insei) as it breaks through a pane or glass was accomplished by shooting the bullet so that it passes Just below two poles of a spark gap; the gases from the firing o' the bullet trail the missile, thus setting off the spark gap, which in turn causes a discharge of 38,000 volts In a partial vacuum, for the necessary illumination. An ordinary miniature camera was used In the experiment. |
