ODD “PINWHEEL CAMERA” CATCHES LIGHTNING (Nov, 1936)
ODD “PINWHEEL CAMERA” CATCHES LIGHTNING
Vagaries of lightning bolts are recorded with a “pinwheel camera” devised by Prof.
John G. Albright of the Case School of Applied Science. At the height of an electrical storm, the shutters of the cameras mounted on a wheel are opened, and the wheel is rotated rapidly by hand. A multiple lightning discharge along a single path is recorded as a series of parallel streaks, and a study of the film gives a clear picture of its behavior. Through the curious arrangement of the cameras, every part of the sky is covered.
