gradient index lens

(optics)
An optical element within which the refractive index is a smooth, but not constant, function of position and, as a result, the ray paths are curved. Also known as graded index lens.

To assure high quality liquid crystal optical elements, pixilation is done by a diffractive approach and gradient index optics are used in relatively thick liquid crystal layers.
