Abstract :
The principle of operation of the simple type of flash-tube stroboscope is described. The development of a ¿slow-motion¿ stroboscope using a phase-shifting potentiometer to maintain a small constant-difference frequency between the frequency of vibration and that of the stroboscopic light source is discussed. Applications of the ¿slow-motion¿ stroboscopes to vibration problems are briefly described.
