    Abstract: Systems and methods for eliminating or mitigating T-effects on Hall sensors. A system may comprise a magnet-coil arrangement for providing a relative movement therebetween to obtain a relative position, a Hall sensor for sensing the relative movement, a temperature sensor located in proximity of the Hall sensor for providing temperature sensing, and a controller having two or more channels coupled to Hall sensor and to the temperature sensor and configured to control the relative movement and to provide, based on the temperature sensing, a temperature correction input to the Hall sensor for compensating a temperature effect on the Hall sensor sensing.

    Abstract: Scanning Tele cameras (STCs) based on two optical path folding element (OPFE) field-of-view scanning and mobile devices including such STCs. A STC may comprise a first OPFE (O-OPFE) for folding a first optical path OP1 to a second optical path OP2, an O-OPFE actuator, a second OPFE (I-OPFE) for folding OP2 to a third optical path OP3, an I-OPFE actuator, a lens, a lens actuator and an image sensor, wherein the STC has a STC native field-of-view (n-FOVT), wherein the O-OPFE actuator is configured to rotate the O-OPFE around a first axis and the I-OPFE actuator rotates the I-OPFE around a second axis for scanning a scene with the n-FOVT, wherein the lens actuator is configured to move the lens for focusing along a third axis, and wherein the first axis is perpendicular to the second axis and parallel to the third axis.
