Abstract
The disclosed device may include a lens stack. The lens stack may include a first gradient-index liquid crystal lens and a second gradient-index liquid crystal lens in tandem with the first gradient-index liquid crystal lens. The lens stack may be configured to reach a target optical power based on a first optical power of the first gradient-index liquid crystal lens and a second optical power of the second gradient-index liquid crystal lens. Various other devices, systems, and methods are also disclosed.
