Abstract
Disclosed are methods and systems for designing beam array generators, or phase masks, utilizing an optimization process which generates an output data set representative of a desired phase grating. Initially an input data set representative of a desired image intensity is received. The output data set comprising a plurality of subsets is defined and initialized. The output data set is traversed by selectively examining ones of the plurality of subsets to determine if a current examined subset represents a phase boundary. Upon such a determination, the output data set is processed as a function of the input data set to improve the quality of the phase grating.
