A Camera for Studying Projectiles in Flight (Classic Reprint)

Excerpt from A Camera for Studying Projectiles in Flight By painting one or more white stripes the full length of the projectile it seems possible to obtain from a series of pictures taken at known intervals the speed of rotation. However, the exposures which have been used are too short to obtain anything but a shadow of the projectile against the sky as a background. By increasing the width of the slots a longer exposure can be made which would give more detail. There is a limit to this, however, as the motion in the direction of rotation is not compensated, and too long an exposure will only produce blurring. Hence, while the measurement of the rotation seems possible, a large amount of experimental work will be necessary to perfect the method.
