The stroboscopic effect is a visual phenomenon caused by aliasing that occurs when continuous rotational or other cyclic motion is represented by a series of short or instantaneous samples (as opposed to a continuous view) at a sampling rate close to the period of the motion.
A bouncing ball captured with a stroboscopic flash at 25 images per second. A strobe light flashing at the proper period can appear to freeze or reverse cyclical motion. A stroboscope, also known as a strobe, is an instrument used to make a cyclically moving object appear to be slow-moving, or stationary.
Illusory motion can occur in different circumstances. Stroboscopic images is where a series of static images are viewed in sequence at a high enough rate that the static images appear to blend into a continuous motion. An example of this is a motion picture.
Stroboscopic conditions ensure that the visibility of a rotating wheel is broken into a series of brief episodes in which its motion is either absent (in the case of movie cameras) or minimal (in the case of stroboscopes), interrupted by longer episodes of invisibility.
The stroboscopic effect is sometimes used to "stop motion" or to study small differences in repetitive motions. The stroboscopic effect refers to the phenomenon that occurs when there is a change in perception of motion, caused by a light stimulus that is seen by a static observer within a dynamic environment.
The phenakistiscope (also known by the spellings phénakisticope or phenakistoscope) was the first widespread animation device that created a fluid illusion of motion. Dubbed Fantascope and Stroboscopische Scheiben ('stroboscopic discs') by its inventors, it has been known under many other names until the French product name Phénakisticope ...
