stroboscope

A stroboscope is a device that produces a rapid sequence of brief flashes of light. The flashes typically occur at regular intervals and can be used to "freeze" the motion of an object or to create an illusion of slow motion. The stroboscope is commonly used in industry to inspect and measure the movement of machinery and other moving parts. It is also used in scientific and medical research, as well as in entertainment, particularly in clubs and music concerts. Stroboscopes can be powered by batteries or by plugging into a power source, and can have varying speeds and flash durations depending on the intended use.
