Introduction:

A stroboscope, also known as a stroboscope or tachymeter, can itself emit short, dense flashes of light. When we adjust the strongpoint of flashing frequency, the analyte and the rotation speed is close to or at the same time, though high speed moving object by test, but the look is slow motion or relatively static, the phenomenon of persistence of vision visual can easily make people observed the running status of the surface quality of high-speed moving objects and the strobe flash the speed of the tested object speed and movement frequency, Also can use the strobe analysis of object vibration, the movement of high-speed moving objects and high-speed photography.
