	STROBOSCOPE, (Site not responding. Last check: 2007-10-12)
		If the stroboscope disk is not in exact synchronism with the moving object, the moving object will appear to move slowly in the direction of its actual motion if the disk is revolving at a slower rate than the object, and slowly in the opposite direction if the disk is turning faster.
		Modern stroboscopes are generally equipped with a light that gives short flashes at the same rate that the moving object is revolving or oscillating.
		Stroboscopes can also be used to adjust the running speed of a machine to the exact rate desired; a simple example of this type is the stroboscopic disk that is used to regulate the speed of phonograph turntables.

	Stroboscope - ArticleWorld
		A stroboscope is an instrument that is used to make a rotating or vibrating object appear stationary or slow moving through the use of flashing lights which intermittently illuminate it.
		Stroboscopes are used in engineering to study stresses on moving objects in machines.
		Stroboscopic disks are used in gramophone turntables to determine their speed.

		In its simplest form the stroboscope is a rotating disk; along its edge are evenly spaced holes through which the moving object is observed.
		If the stroboscope is not quite synchronized with the object's motion, the object will appear to move slowly either backward or forward, depending upon whether the stroboscope's rotation is too fast or too slow.
		When used in conjunction with a camera a stroboscopic light can also be used to study motion that is not cyclic, e.g., a speeding bullet; the resulting photograph shows a series of still images whose separations are proportional to the object's speed.

	Stroboscope - GenRad Stroboscopes
		The Stroboslave, whose light output is the same as that of the 1531-AB stroboscope, was designed specifically for the many applications where motion study or photography, rather than speed measurement, is required.
		This stroboscope was designed specifically for inspection applications and features a simple pushbotton controal with a single knob to control the flash rate -no switching is ever necessary.
		The stroboscope also may be operated from any flat surface or mounted on a tripod.

	Stroboscope Summary
		Stroboscopes are used in industry to study the movement of machinery and in science to analyze objects as they undergo rapid, cyclic motion, making the objects appear stationary or nearly so by matching the stroboscope's rate of flashing to the object's frequency of motion.
		The illusion is caused by temporal aliasing, commonly known as the 'stroboscopic effect'.
		Joseph Plateau of Belgium is generally credited with the invention the stroboscope in 1832, when he used a disc with radial slits which he turned while viewing images on a separate rotating wheel.

	Stroboscope
		A stroboscope is a flashing light source used to measure the speed of fast-moving objects.
		The stroboscope can be used to measure the speed and to observe the motion of rotating, reciprocating, or vibrating mechanisms.
		Since the stroboscope makes a moving object appear to be standing still, someone could be seriously injured by the apparently “stationary” object.

	Trigger circuits for stroboscopes
		Stroboscope circuit use lethal voltages, so you must be very careful when operating with them.
		If you are modifying an actual stroboscope light, my 12V strobocope circuit will give you some idea how to use a transformer isolated trigger circuit in a real stroboscope circuit.
		When you do the installation, be sure that the stroboscope is diconnected from the power source and all capacitors are discharged, before you even think of touching the circuit.

	Simplified Stroboscopic System for Motion Pattern photography
		With the advent of the electronic flash and the electronic stroboscope, and primarily under the guidance of Harold Edgerton from the 1930's through the 1980's, the recording of subjects in motion onto a stationary film (and less well known, onto moving film) became almost the exclusive domain of electronic stroboscopes.
		A mechanical stroboscope consists of a rotating disc with a radial slot cut into it and the disc placed in front of a camera's lens in such a manner that each time the slot passes by the lens the camera sees the subject for a brief time interval.
		Traditional stroboscopic techniques generally have concentrated on simply opening the shutter at the beginning of the action and closing it at the end and recording the moving subject during the process.

		When the stroboscope is triggered externally, the flash rate and phase will automatically be synchronized with the trigger signal.
		When selecting a Stroboscope consider the speed of the equipment you wish to observe, the type of environment how bright the light should be and the triggering options.
		Stroboscopes can be used with video inspection systems for high speed packaging, with vibration data collectors to provide phase studies and operational deflection shape (ODS) analysis, to aid in dynamic balancing and the list goes on.

		Thus, a stroboscope set to flash at the motor's fundamental frequency can be used to visually observe when the rotor's angular displacement has changed, and the stroboscope can be used to slow down periodic motion enough that the human eye can perceive it.
		Edgerton was able take motion pictures at 6,000 frames per second by using a stroboscope instead of a continuous light source, and pulling the film through the camera at 100 feet per second.
		This stroboscope increased the illumination of the object, allowed flashes of shorter duration at controllable intervals, and facilitated several observers at once.

	An LED Stroboscope
		This can be performed using either a tachograph, which directly measures the speed, or a stroboscope, which compares the speed with a know frequency.
		Tachographs are slightly more complicated to make than a stroboscope, since you need to attach a device to the motor that can affect an external device which then counts the number of disturbances in a given time frame.
		Here I present the design of a stroboscope, and describe how it can be used to measure the rotational speed of a motor, or wheel.
