Abstract:
Actuators for providing an extended two-degree of freedom rotation range to an optical path folding element (OPFE) such as a prism or mirror in mobile devices such as smartphones, comprising a yaw sub-assembly having a yaw rotation axis, a pitch sub-assembly carrying the OPFE, the pitch sub-assembly including a pivot rotation mechanism and having a pitch rotation axis; and a stationary sub-assembly, wherein the actuator is operative to rotate the OPFE in two rotation directions, a first rotation for yaw around the yaw rotation axis and a second rotation for pitch around the pitch rotation axis, and wherein the rotation for pitch includes rotation using the pivot rotation mechanism.
