Abstract
A method for fabricating a liquid crystal phase modulation device is provided. The method includes detecting thicknesses of a plurality of portions of a reference liquid crystal layer of a reference liquid crystal phase modulation sample; determining a distribution according to the thicknesses of the portions of the reference liquid crystal layer; forming a plurality of spacers over a first substrate in the determined distribution; and combining the first substrate with a second substrate and a liquid crystal layer to form the liquid crystal phase modulation device.
