Abstract
A method of controlling the resolution of an optical encoder for providing position information of an object which moves along a certain measuring direction where the optical encoder includes a light source that emits light and a data track that moves relative to the light source. The method includes directing modulated light from the data track to a plurality of photodiodes of a detection system having a resolution that has a first value and changing the resolution of the detection system to a second value without altering an arrangement of the plurality of photodiodes of the detection system during the changing from the first value to the second value.
