|1.||Sometimes shortened to: strobe an instrument producing a flashing light, the frequency of which can be synchronized with some multiple of the frequency of rotation, vibration, or operation of an object, etc, making it appear stationary. It is used to determine speeds of rotation or vibration, or to adjust objects or parts|
|2.||a similar device synchronized with the opening of the shutter of a camera so that a series of still photographs can be taken of a moving object|
|[C19: from strobo-, from Greek strobos a twisting, whirling + |
A lamp that produces very short, intense flashes of light by means of an electric discharge in a gas. The ability of strobe lights to "freeze" the motion of rapidly moving objects by making them visible for only a fraction of a second makes them very useful in photography and in measuring vibration and other types of high-speed motion.
