摘要:

A stroboscopically illuminated turntable is described; accurate and easily manipulated variation of the flashing frequency relative to the turntable frequency is achieved by photoelectric triggering of the lamp. The device is suitable for both visual and photographic evaluation of objects that may possess ``hidden'' degrees of radial (rotational) symmetry.
