Abstract:

A simple experimental test was done to examine the optical effect of a light beam sent up the wake of a projectile. The results show that the wake acts as a diverging lens to this light beam. Measurements of the optical deviation were made. Some consequences of this effect on certain miss-distance indicators are discussed.
