Abstract
Actuators for rotating an optical-path-folding-element with two, first and second, degrees of freedom in an extended rotation range around two respective rotation axes, folded cameras including such actuators and dual-cameras including a folded camera as above together with an upright camera.
Claims8
A sensing mechanism for sensing rotation movement around a rotation axis, comprising:
- a) a magnet;
- and
- b) a magnetic sensor configured to detect a magnetic flux of the magnet and to determine a relative shift between the magnet and the magnetic sensor based on change in the detected magnetic flux,
- wherein the magnet is shaped such that a cross section of the magnet has a width that increases from a point substantially at a center of the magnet towards each end of the magnet, thereby increasing a range of detectable change in the magnetic flux and increasing a corresponding detectable range of the relative shift between the magnet and the magnetic sensor.
