Abstract
An inductive type position encoder includes a scale, a detector portion and a signal processor. According to one aspect, field generating elements and sensing elements of the detector portion are provided on opposite sides of the scale such that at least part of the scale is between the field generating elements and the sensing elements (transmissive configuration). According to another aspect, the scale comprises a periodic scale pattern including signal modulating elements that are disposed along a scale direction, which is not parallel to a measuring axis direction of the encoder and is slanted at a scale angle relative to the measuring axis direction, such that there is a corresponding y-direction displacement for a given x-direction displacement of the encoder. These aspects of the disclosure make it possible to design a very compact inductive type position encoder, including one capable of indicating an absolute position along the scale.
