Abstract:
Aspects of the present disclosure generally relate to optical devices and related methods that facilitate tilt in camera systems, such as tilt of a lens. In one example, an optical device includes a lens, an image sensor disposed below the lens, a plurality of magnets disposed about the lens, and a plurality of: (1) vertical coil structures coiled in one or more vertical planes and (2) horizontal coil structures coiled in one or more horizontal planes. When power is applied, the coil structures can generate magnetic fields that, in the presence of the magnets, cause relative movement of the coil structures and associated structures. The plurality of vertical coil structures are configured to horizontally move the lens. The plurality of horizontal coil structures are configured to tilt the lens when differing electrical power is applied to at least two of the plurality of horizontal coil structures.
