Abstract
A target for an inductive displacement sensor is provided, including a plurality of conductive patterns distributed along a zone having a dimension Dtot in a direction, the patterns being defined by the overlay of at least a first set of elementary periodic patterns having a period approximately equal to Dtot/N, including N first elementary conductive patterns of a dimension approximately equal to Dtot/2N in the direction, regularly distributed along the zone, and of a second set of elementary periodic patterns having a period approximately equal to Dtot/(N+r), including N+r second elementary patterns of a dimension approximately equal to Dtot/2(N+r) in the direction, regularly distributed along the zone, where N is an integer greater than or equal to 2 and r is a positive integer, different to zero and less than or equal to N−1, wherein first and second elementary conductive patterns overlap at least partially.
