Abstract
A method for designing a diffractive optical element comprises: determining parameters of a light source and a target light field of a diffractive optical element; according to the parameters of the light source, determining the distribution of a plurality of first microstructure units on the diffractive optical element; dividing the target light field into a plurality of target maps superimposed to form the target light field, the first microstructure units corresponding to the target maps; performing distortion pre-correction on the plurality of target maps separately; and according to the plurality of corrected target maps and the parameters of the light source, designing corresponding phase distributions of the plurality of first microstructure units separately. A VCSEL partitioned light source may be combined with a diffractive optical element to project a uniform light field. The diffractive optical element is applied to a partitioned illumination system, which provides a uniform illumination.
