stroboscopes
Rapid flash devices
Stroboscopes are instruments that produce rapid flashes of light at adjustable intervals, used to make rotating or vibrating objects appear stationary or slow-moving.
Engineers use them to study machinery in motion without stopping it.
The principle underlies strobe lights at dance clubs, where the flashing creates a choppy, freeze-frame effect on dancers' movements.
