A stroboscope is a light source that flashes at a certain frequency. When using a stroboscope to observe a high-speed rotating or moving object, by adjusting its flicker frequency to make it close to and synchronized with the rotation or moving speed of the measured object, although the measured object is moving at high speed, it looks It is moving slowly or relatively static. 

This phenomenon of persistence of vision allows people to easily observe the operating conditions of high-speed moving objects. Such as various types of rotors, gear meshing, vibration equipment diagnosis, textile, printing, packaging production lines, surface defects and running tracks of high-speed objects. 

The stroboscope is widely used in machinery manufacturing, printing, light industry, textile, electric power, medicine, food processing and other industries.
