==Simplified Explanation==

The patent application is for a diffractive optical element that is made up of multiple unit cells arranged on a substrate.
Each unit cell consists of multiple phase elements, with each phase element having a specific phase value.
The phase values are determined by multiplying an incremental phase value by an index value.
The index value ranges from 1 to N, and N is the total number of phase values.
The diffractive optical element is designed to have M phase elements, where M is greater than 1.
The innovation lies in the arrangement and characterization of the phase elements in the diffractive optical element.


==Original Abstract Submitted==

A diffractive optical element includes a substrate including a plurality of unit cells arrayed across the substrate. Each of the unit cells includes M phase elements and each of the M phase elements is characterized by one of a set of N phase values. Each of the set of N phase values is equal to an incremental phase value times an index m, wherein M>1 and m=1 . . . N.
