What is a stroboscopic effect?
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.
What is a stroboscopic flash?
A bouncing ball captured with a stroboscopic flash at 25 images per second. 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.
What is an example of stroboscopic motion?
A strobe fountain, a stream of water droplets falling at regular intervals lit with a strobe light, is an example of the stroboscopic effect being applied to a cyclic motion that is not rotational.
What is meant by stroboscopic?
noun. a device for studying the motion of a body, especially a body in rapid revolution or vibration, by making the motion appear to slow down or stop, as by periodically illuminating the body or viewing it through widely spaced openings in a revolving disk.
What is the stroboscopic effect in psychology?
the apparent motion of a series of separate stimuli occurring in close consecutive order, as in motion pictures. 2. the apparent motionlessness or reverse motion of a moving object, such as a rotating fan, produced by illuminating it with a series of intermittent light flashes. Also called stroboscopic effect.
What does a stroboscope look like?
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.
Where is stroboscope used?
Stroboscopes are used to measure revolutions, velocity and frequency of rotating components or moving parts. Online you will be able to find stroboscopes by PCE and several other companies. Some stroboscopes can be used without a mains adaptor as they have rechargeable batteries and each model is light and easy to use.

Can flashing lights make you sick?
Strobe lights and vertigo Strobe lights have been known to cause flicker vertigo, a condition in which disorientation, nausea, rapid blinking, rapid eye movement, and muscle rigidity are known symptoms.
Who discovered stroboscopic effect?
physician Peter Marc RogetThe stroboscopic effect was observed and documented as early as the early 19th century by the English physician Peter Marc Roget. His observations led to the development of stroboscopy, an optical method for making fast, periodic motion sequences visible.

What is a stroboscopic tachometer?
A stroboscope, also called a strobe light or strobe tachometer, can be used to measure the rotation speed or revolution velocity and frequency of rotating, vibrating or moving parts, components and equipment. The flash frequency of a stroboscope is adjustable to ensure accurate measurement of these parameters.

What is a stroboscope?
The term stroboscope sometimes refers to more specialized devices used for these specific purposes. Example: By using a stroboscope, we were able to capture the extremely rapid wing beats of a hummingbird.
Where did the word "stroboscope" come from?
Where does stroboscope come from? The first records of the word stroboscope come from around the 1830s. The first part of the word comes from the Greek strobos, meaning “a twisting” or “a whirling.”. The ending, -scope, is used in the names of other optical tools, such as telescope and microscope.
What is a strobe light?
Stroboscope is another name for a strobe light —a type of specialized lamp that produces a continuous series of short, bright flashes of light. They can also be called strobes or stroboscopic lamps. The kind of rapid flashing produced by a stroboscope (called strobe lighting) has the effect of seeming to freeze the movement of things in motion.
What does the ending "scope" mean?
The ending, -scope, is used in the names of other optical tools, such as telescope and microscope . The adjective form of stroboscope, stroboscopic, is used in the terms stroboscopic lamp (a synonym for stroboscope) and stroboscopic microscope (a specialized microscope that uses a strobing effect to aid in observations).
What is a stroboscope used for?
In medicine, stroboscopes are used to view the vocal cords for the diagnosis of conditions that have produced dysphonia (hoarseness). The patient hums or speaks into a microphone which in turn activates the stroboscope at either the same or a slightly different frequency.
How does a stroboscope work?
In its simplest mechanical form, a stroboscope can be a rotating cylinder (or bowl with a raised edge) with evenly spaced holes or slots placed in the line of sight between the observer and the moving object. The observer looks through the holes/slots on the near and far side at the same time, with the slots/holes moving in opposite directions. When the holes/slots are aligned on opposite sides, the object is visible to the observer.
When was the strobe light stroboscope invented?
The electronic strobe light stroboscope was invented in 1931, when Harold Eugene Edgerton ("Doc" Edgerton) employed a flashing lamp to study machine parts in motion. General Radio Corporation then went on to produce this invention in the form of their "Strobotach".
What is a bright stroboscope?
Bright stroboscopes are able to overpower ambient lighting and make stop-motion effects apparent without the need for dark ambient operating conditions. They are also used as measuring instruments for determining cyclic speed. As a timing light they are used to set the ignition timing of internal combustion engines .
Who invented the stroboscope?
Joseph Plateau of Belgium is generally credited with the invention of the stroboscope in 1832, when he used a disc with radial slits which he turned while viewing images on a separate rotating wheel. Plateau's device became known as the " Phenakistoscope ". 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".
What is a strobe flash?
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.
What frequency is stroboscopic?
Stroboscopic effect becomes visible if the modulation frequency of the TLM is in the range of 80 Hz to 2000 Hz and if the magnitude of the TLM exceeds a certain level. Other important factors that determine the visibility of TLMs as stroboscopic effect are:
What is the stroboscopic effect on a disc?
The stroboscopic effect also plays a role in audio playback. Compact discs rely on strobing reflections of the laser from the surface of the disc in order to be processed (it is also used for computer data ). DVDs and Blu-ray Discs have similar functions.
What is a strobe fountain?
A strobe fountain, a stream of water droplets falling at regular intervals lit with a strobe light, is an example of the stroboscopic effect being applied to a cyclic motion that is not rotational. When viewed under normal light, this is a normal water fountain. When viewed under a strobe light with its frequency tuned to the rate at which ...
