A stroboscope is an instrument for observation and measurement that emits a high-speed blinking light. By turning the light on and off instantly and repeatedly, it is possible to analyze the trajectory and momentum of an irradiated object.
They can be broadly classified into two categories: those that are activated by setting the number of blinks per unit time and those that are activated by an external signal. The former is mainly used to measure the state of movement, while the latter is used to measure timing.
A wide variety of products are available from various companies, ranging from portable size for personal use to relatively large ones for industrial use.
Stroboscopes are mainly used for calibration of products such as tape recorders and record players, whose performance is directly related to RPM, and for engine ignition timing adjustment.
In the case of calibration work, if a disk rotating at the specified speed of 100 RPM is marked and illuminated by a stroboscope set to blink 100 times per minute, the disk and the marked area will appear to stop. Therefore, if the rotation speed is slower than the specified speed, the stroboscoped object will appear to be rotating in reverse at 1 RPM, and it can be determined that calibration is necessary.
When used to adjust the ignition timing of an engine, the strobe is illuminated at the timing when the first cylinder is ignited by the spark plug by interrupting the signal line to the ignition circuit of the first cylinder. Therefore, the point where the scale on the crank pulley and the mark on the cylinder block coincide can be read to determine the ignition timing.
In either case, "whether or not adjustment is necessary" and "the result of adjustment" appear visually in real time, enabling efficient work.
A major feature of the stroboscope is that it utilizes the optical illusion created by the afterimage phenomenon of the retina. Similar to the time-lapse photography technique used in the video industry, the stroboscope can instantaneously capture the motion of an object by means of flickering light.
Other instruments for measuring motion include rotation sensors, acceleration sensors, and position sensors. In addition to the two examples above, the stroboscope has the advantage of being highly versatile, as it can be used to observe chemical reaction processes and to diagnose throat cancer. However, since stroboscopes are instruments that use light and contrast, they also have the disadvantages of requiring illumination from an appropriate distance and direction, being unsuitable for use in bright locations, and causing white-out if the contrast between light and dark is too large. There are also automatic-exposure types equipped with an exposure meter, but they cannot be used for measurement in extremely bright environments, especially outdoors during the daytime.
Xenon flash lamps provide a large amount of white light, while LED lamps provide a long life with low power consumption, and can change light colors without sacrificing brightness, which is a feature unique to LEDs. LED lamps have the unique feature of "low power consumption and long life.
The flashing light from a stroboscope is intended to be used to illuminate an object with a large amount of light, so direct observation by the naked eye is contraindicated.
