【Abstract】 The design method for diffractive microlens arrays,the data struc t ure of CIF format mask data and their generating method are investigated in the paper.A practical software is designed.The problems in generating the masks for d iffractive microlens arrays with sub-aperture shapes of rectangular,hexagon,cir que-sector are solved by adopting the methods of image segmentation and trackin g algorithm,thus the various requirements of the practical systems for the sub- apertures of the diffractive microlens arrays are fulfilled.更多还原
