Optical speed
WebOptical speed bars give drivers the impression they are traveling faster than they really are, causing them to slow down at curves, such as on this roadway in Virginia. Cathy … WebThe optical encoder is a transducer commonly used for measuring rotational motion. It consists of a shaft connected to a circular disc, containing one or more tracks of alternating transparent and opaque areas. A light source and an optical sensor are mounted on opposite sides of each track.
