Abstract: Inductance-based sensing in a digital camera in which actuation of at least one electromagnetic (EM) actuator that includes at least one stationary ferromagnetic member associated with a large air gap causes a moving ferromagnetic member mechanically coupled to an optical element to by-pass or bridge the large air gap through at least one smaller air gap. The stationary member includes at least one ferromagnetic core surrounded at least partially by a coil. An inductance value correlated with a position of the optical element may be measured using the same coil as the one used for the actuation. In some embodiments, a single EM actuator includes two coils and the actuator is driven using both coils, while a regular or a mutual inductance is measured. In some camera embodiments that include two opposite EM actuators, one actuator is used to move the optical element while the other actuator is used to measure the inductance value.

Abstract: Electro-magnetic actuators used to provide a displacement of an optical element such as a lens carrier comprise at least one ferromagnetic frame associated with a large air gap and at least one ferromagnetic member parallel to and separated from an elongate section of a frame by a small air gap. Actuation causes a magnetic circuit that appears in the at least one frame, the at least one member and small air gaps and by-passes or bridges the large air gap. In some embodiments, the resultant magnetic force moves the at least one member and leads to the displacement of an optical element attached thereto. In some embodiments, at least one frame and at least one member are arranged to provide a center hole and are dimensioned to enable insertion of a lens carrier in the hole. In some embodiments, the displacement is for auto-focus or for optical image stabilization.
