Abstract
A lens device includes a substrate having a channel and a first fluid flow path and a second fluid flow path. The first and second fluid flow paths at least partially in communication with the channel. A light emitting device is positioned adjacent to the channel. At least one first fluid source is in communication with the first fluid path such that a first fluid is moveable along the first fluid path and at least one second fluid source in communication with the second fluid path such that a second fluid is moveable along the second fluid path. The first second fluid paths are configured so the first fluid and second fluid move through the channel to define an adjustable liquid gradient refractive index distribution in the channel. Adjustment of the liquid gradient refractive index distribution permits a change of liquid lens focal distance or an angular adjustment of light emitted by the light emitting device.
