Abstract
An optical encoder includes an encoding disk and an optical detector disposed to correspond to the encoding disk. The optical detector includes a plurality of optical sensors arranged to form an optical sensor array. The optical detector is provided to receive light. The optical detector includes at least one optical sensor arranged to form at least one sensor array. The width of the sensor array corresponds to an interpolation period of the optical encoder.
