It's a calibrated flashing light used to measure the rotational speed of, say, a spinning motor shaft. Like the timing light used by mechanics on a car. The strobe is variable, and it can be "run up" until the flashing light on the spinning object causes the object to "stand still" and not appear to move. Then a peek at the readout of the strobe, and the user will know how fast the object is turning. Note that the shaft doesn't stop turning, but the strobe flashes and it illuminates the same spot on the shaft with every rotation, and that's what makes it (the shaft) appear to stop moving. All the operator need to be concerned about is avoiding a harmonic. If the strobe is flashing at exactly half the speed of the shaft, it will be illuminating the same spot on the shaft each time it flashes, but the shaft will actually have turned twice instead of once. But a good operator can avoid that.

∙ 10y agoA stroboscope is an instrument that is used to make objects that move cyclically appear to be stationary or slow in movement. The two types of stroboscopes are mechanical and electronic.

Principle of stroboscope?
The principle of a stroboscope is to study rotating, reciprocating, oscillating, or vibrations in objects. A stroboscope is used to make cyclically moving objects appear stationary or slower.
What are the units for stroboscope?
my guess is rpm
What is the equipment called for measuring fan speed?
Stroboscope.
How can you use a stroboscope to find the pitch of a tuning fork?
bhb
What does a stroboscope look like?
A stroboscope is usually just a lamp, set to flash quickly and repeatedly with an often tuneable and consistent frequency. Strobes used to set the ignition timing on engines with spark plugs usually look a bit like a gun, but otherwise they can look like pretty much any lamp.
What is the definition of the word stroposcopes?
A stroboscope is any various instrument used to observe moving objects by making them appear stationary, especially with pulsed illumination or mechanical devices that intermittently interrupt observation.
What are the three primary scientific targets that were photographed by the astronomical telescope Stratoscope II?
Planetary atmospheres, the atmospheres of red giant stars, and galaxies were the three primary scientific targets of Stroboscope II.
Where is a stroboscopic tachometer used?
A stroboscope uses a series of flashes to make a fast moving object seem slower. A stroboscopic tachometer has a scale that reads either in revolutions per minute or flashes per minute.
What year was the strobe light invented?
The history of strobe lighting dates to 1931, when Harold Eugene Edgerton employed a flashing lamp to make an improved stroboscope for the study of moving objects, resulting in photographs of objects such as bullets in flight.
What is strobe?

How do you measure mechanical frequency?
I assume you mean measure the frequency of vibration of a mechanical system or part. You use a stroboscope, which is a light that flashes briefly and rapidly. You shine the light on the object and adjust the frequency of the strobe by turning a dial until the object stops moving. You then read the dial to determine the frequency. there are steps you have to take to avoid synchronizing to a subharmonic of the base frequency. For example, if the object is vibrating at 100Hz (10ms), running the strobe at 50hz will also stop the motion, as it will pick up every other cycle.
How are echoes used to measure distances under water?
H E Edgerton, improved greatly on the stroboscope and this was made widely available by General Electric. Strobes had been invented more than a hundred years earlier in Belgium. He then went on to improve sonar, by introducing the element of 'side-scan' sonar, with which many pictures of the ocean floor are made. These have much more resolution and display than 'ping' sonar.
