A stroboscope, also known as a strobe, is an instrument used to make a cyclically moving object appear to be slow-moving, or stationary. It consists of either a rotating disk with slots or holes or a lamp such as a flashtube which produces brief repetitive flashes of light. Usually, the rate of the stroboscope is adjustable to different ...
It is one of a number of devices that can be used as a stroboscope. The word originated from the Ancient Greek στρόβος ( stróbos ), meaning "act of whirling". A typical commercial strobe light has a flash energy in the region of 10 to 150 joules , and discharge times as short as a few milliseconds, often resulting in a flash power of ...
Stroboscopic effect is one of the particular temporal light artefacts.In common lighting applications, the stroboscopic effect is an unwanted effect which may become visible if a person is looking at a moving or rotating object which is illuminated by a time-modulated light source.
An old method of measuring the frequency of rotating or vibrating objects is to use a stroboscope. This is an intense repetitively flashing light (strobe light) whose frequency can be adjusted with a calibrated timing circuit. The strobe light is pointed at the rotating object and the frequency adjusted up and down.

When it was introduced in the French newspaper Le Figaro in June 1833, the term 'phénakisticope' was explained to be from the root Greek word φενακιστικός phenakistikos (or rather from φενακίζειν phenakizein), meaning "deceiving" or "cheating", [2] and ὄψ óps, meaning "eye" or "face", [3] so it was probably intended loosely as 'optical deception' or 'optical illusion'.
Stroboscopic may refer to: . Stroboscopic effect, visual temporal aliasing; Stroboscopic effect (lighting), a temporal light artefact visible if a moving object is lit with modulated light with specific modulation frequencies and amplitudes
