ABSTRACT:
An absolute displacement detector utilizing two sensors and a code bearing track having domains arranged such that relative movement between the sensors and the track produces two signals in phase quadrature which are processed with digital circuitry to provide displacement data indicated by a multiple bit digital word whose higher bits indicate number of domains passed and whose lower bits indicate position within a domain.
