Abstract

The use of stroboscopic patterns for fixing and measuring rotational speeds is discussed. Patterns having as many as nine bands may be utilized. The patterns occur in a definite recurring sequence, according to a simple numerical relation. Most of the speeds intermediate to those at which patterns are stationary may be obtained by correcting for the precession or recession of the patterns.
