Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  F  H | IPC F  G  H

Claim 0:
1. A method of imaging, the method comprising:
controlling phase shifts provided by each of a plurality of liquid crystal cells included in an array, the array further including a plurality of patches with each patch having a set of liquid crystal cells of the plurality, such that each liquid crystal cell of a set of liquid crystal cells within a given patch provides a respective phase shift to electromagnetic radiation passing through the liquid crystal cell so that the given patch forms a corresponding lens that focuses electromagnetic radiation, wherein the plurality of liquid crystal cells are arranged in a planar configuration, such that a first surface of each liquid crystal cell of the plurality of liquid crystal cells define a first surface of the array, and a second surface of each liquid crystal cell of the plurality of liquid crystal cells define a second surface of the array, wherein electromagnetic radiation incident on the first surface of the array exits from the second surface of the array, and wherein said controlling includes controlling the phase shifts of the liquid crystal cells of a plurality of the patches to form a plurality of lenses corresponding with the plurality of patches that focus electromagnetic radiation; and
detecting the electromagnetic radiation that has passed through the liquid crystal cells.
