Using inhomogeneous sized liquid crystal (LC) droplets for lens and
prisms. For forming a positive lens, the LC droplet size can gradually
increase from the center to the side edges. For forming a negative lens,
the LC droplet size can gradually decrease from the center to the side
edges. The lens can be created by Ultra Violet light exposure to
patterns. The lens can be tuned by applying voltage to the droplets. The
inhomogeneous droplets can also be used in Fresnel lens and prisms.
Applications of the invention can be used for eyeglasses, arrays, camera
type zoom lenses and beam steering applications.
