Claim 11:
12. An imaging device comprising:
a liquid crystal spatial light modulator comprising liquid crystal cells arranged in a plurality of patches, such that the liquid crystal spatial light modulator includes at least (i) a first patch including a first plurality of liquid crystal cells, and (ii) a second patch including a second plurality of liquid crystal cells, wherein each liquid crystal cell is configured to provide a respective phase shift to electromagnetic radiation passing through the liquid crystal cell, wherein the liquid crystal cells are arranged in a planar configuration, such that a first surface of each liquid crystal cell define a first surface of the plurality of patches, and a second surface of each liquid crystal cell define a second surface of the plurality of patches, and wherein electromagnetic radiation incident on the first surface of the plurality of patches exits from the second surface of the plurality of patches;
a detector;
control electronics for controlling the phase shifts provided by each liquid crystal cell of the first and second plurality of liquid crystal cells, such that each of the first and second patches focuses electromagnetic radiation towards the detector; and an image processor for generating an image from electromagnetic radiation detected by the detector.
