ABSTRACT:
Apparatus for detecting relative displacement includes a first magnet for producing a first magnetic field along an axis; a second magnet for producing a second magnetic field along the axis; the first and second magnetic fields interacting to produce a position-dependent magnetic field along the axis; a sensor disposed for detecting the position-dependent magnetic field; and a movable element for causing relative displacement between the position-dependent magnetic field and the sensor. In a preferred embodiment, the sensor is a magneto-optic sensor.
