| description | The invention provides a measurement sensor for determining the position of a moving body, the sensor comprising a series of at least four detector probes for detecting a physical magnitude coming from a target comprising at least one track for creating a physical magnitude that is measurable by the detector probes and that varies along the path of the target with a function that is continuous and that includes a first harmonic and a second harmonic, the probes being connected to a processor unit for processing signals delivered by the probes, the processor unit including a reconstruction system for performing a linear combination of the signals and for obtaining firstly two quadrature signals including solely the first harmonic, and secondly two quadrature signals including solely the second harmonic, the unit also including a calculation system for processing the quadrature signals in order to determine the position of the moving body. |
