STROBOSCOPE


Meaning of STROBOSCOPE in English

n.

Instrument that repeatedly illuminates a rotating or vibrating object in order to study the motion of the object or to determine its rotation speed or vibration frequency.

The effect is achieved by producing light in very short bursts timed to occur when the moving part is in the same phase of its motion. By use of the stroboscope, a machine part, for example, may be made to appear to slow down or stop.
