stro·bo·scope

(strō'bō-skōp),
An electronic instrument that produces intermittent light flashes of controlled frequency; used to influence electrical activity of the cerebral cortex.

stroboscope

(strō′bō-skōp) [Gr. strobos, whirl, + skopein, to examine]
A device that produces light intermittently. When the light is shown on moving or vibrating objects, the object appears to be stationary. A photograph taken at the precise time the light is flashed on the object will not be blurred.

stroboscope 

An instrument that produces brief flashes of illumination at a variable frequency. The frequency can be synchronized or asynchronized with the frequency of a moving object, which can be made to appear stationary, to rotate slowly or to rotate in the opposite direction to its real rotation. This apparent change of motion or immobilization of an object, when the object is illuminated by a periodically varying light of appropriate frequency, is called a stroboscopic effect. Stroboscopes have various uses in medicine, industry (e.g. to study the stresses of machine parts in motion), scientific research, etc. See stroboscopic movements.
