Abstract:
1. A lens device comprising: a substrate having a channel and a first fluid path and a second fluid path, the first and second fluid paths at least partially in communication with the channel; a light emitting device positioned adjacent to the channel; at least one first fluid source in communication with the first fluid path such that a first fluid is moveable along the first fluid path; 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; and the first fluid path and the second fluid path configured such that the first fluid and the 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 permitting at least one of an angular adjustment of light emitted by the light emitting device and an adjustment of a focal distance of the light emitted by the light emitting device; and wherein the at least one first fluid source and the at least one second fluid source are each comprised of a solution inlet and at least one water inlet.
