There was an almost simultaneous and independent invention of the device by the Austrian Simon Ritter von Stampfer, which he named the "Stroboscope", and it is his term which is used today. The etymology is from the Greek words στρόβος - strobos, meaning "whirlpool" and σκοπεῖν - skopein, meaning "to look at".
Consider the stroboscope as used in mechanical analysis. This may be a "strobe light" that is fired at an adjustable rate. For example, an object is rotating at 60 revolutions per second: if it is viewed with a series of short flashes at 60 times per second, each flash illuminates the object at the same position in its rotational cycle, so it ...
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
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 ...
A thaumatrope is an optical toy that was popular in the 19th century. A disk with a picture on each side is attached to two pieces of string. When the strings are twirled quickly between the fingers the two pictures appear to blend into one.
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'.
A replica of a Victorian zoetrope. A zoetrope is a pre-film animation device that produces the illusion of motion, by displaying a sequence of drawings or photographs showing progressive phases of that motion.
Videostroboscopy is a high-speed medical imaging method used to visualize the dynamics of human vocal fold vibration.. When stimulated by the pressure of breath exhaled from the lungs, the two vocal folds (also known as vocal cords) open and close rapidly.
