1. An optical path folding element (OPFE) actuation sub-assembly, comprising:
a voice coil motor (VCM) actuator for actuating the OPFE to tilt around a virtual hinge axis positioned externally to the OPFE, the VCM actuator including a magnet rigidly coupled to the OPFE and a coil rigidly coupled to a base; and
a Hall-bar located in proximity of the coil or located within a vacant area in the middle of the coil and used for measuring a magnetic field in the Hall-bar correlated with an amount of tilt of the OPFE,
wherein the OPFE has an OPFE object-facing surface and an OPFE height HOPFE measured along a height axis perpendicular to the OPFE object-facing surface,
wherein the virtual hinge axis is located at a distance D from the Hall-bar, the distance D measured along the height axis,
and wherein D>HOPFE to increase a relative motion between the magnet and the Hall-bar for a given tilt angle of the OPFE.
