WebHow does an optical encoder work? Just like magnetic and inductive encoders, optical encoders work with a ruler. With optical technology, the ruler consists of a pattern of reflectors, or the light-sensitive layer. If an object moves, the encoder is moved across the ruler. These rulers are available in both straight and round versions. WebThe encoders use rotating discs with optical windows, as shown in the figure below. The encoder contains an optical disk with fine windows engraved on it. The light from the …

WebThe encoder can be either incremental or absolute. In an incremental system, position is determined by motion over time; in contrast, in an absolute system, motion is determined by position over time. Linear encoder technologies include optical, magnetic, inductive, capacitive and eddy current.
